Russian scientists have proposed innovative design of solar cells

Innovators of the university enterprise SibInvent-Cosmos in Krasnoyarsk have developed an original design of solar batteries for space and ground use, which are capable of higher efficiency than all other Russian analogues. Skolkovo promises to help start the production of these cheap solar cells.

Technical director of the company, Boris Shagarov, told about the following technology: “A super-thin, 5-20 micrometers thick microelectric converter (FEP) is produced on the basis of monocrystalline silicon. It is assembled into an original double-sided isogride design,
which provides effective photon absorption across the entire spectrum of solar radiation with a possible efficiency of up to 28% at a concentration in the 300 suns. This is a space option - with ground-based devices, the efficiency will be 25%. ”

The idea has already been tested by specialists, and even a photo response was obtained on a prototype. “For further development, you need expensive equipment, which is not yet available in Russia,” local newslab.ru quoted Shagarov as saying. A chance for its acquisition can give entry into the Skolkovo Foundation.

The competitors of these Krasnoyarsk designers are the companies Kvant and Hevel (both are Russia). “Their amorphous batteries are now trying to replace ordinary planar solar cells, on the assumption that they are lighter and cheaper. But if we use our design, compared with the amorphous, the flight weight will be three times less, and the efficiency will be two to three times more: for Kvant, the efficiency is 9%, for Hevel - 11%, ”says Shagarov .

At present, the engineers of this Krasnoyarsk company are filling out an application and have already received preliminary approval of their project from the experts of the Space Technologies and Telecommunications Cluster of the Foundation at the conference “Innovations in Space Industry” held in Krasnoyarsk.

Solar energy is a very promising area both in space and in the civilian sphere, and scientists must capture our market and supplant adversaries.

The fact that competition is taking place among Russian companies is also encouraging!

I do not quite agree. The main thing is that the east does not flow away. The Chinese have already sent a scout.
In the West, I’ve been straining with money now. Open a new production for them is now akin to a feat. But in China, the money is rampant. And they are no less than Geyropa want to get rid of volatility. I regularly hear from Chinese directors (I have been working with the Chinese for 8 years) that they say - brazen Russians are pumping resources from our original Chinese territory, and then they are selling to us. Moreover, knowing that I speak Chinese, they are not at all embarrassed to express their claims to each other on our territory! Pay attention, the educated Chinese elite says so! What can we say about ordinary Chinese - they sleep and see the territory to their Urals!
So, God forbid, this technology will go to China (as I understand it, the technology is not the most effective, but rather simple, and, therefore, quite cheap). They will immediately establish production - there’s no time for investment!

[Cosmos-1869]

Here are just Russian companies, instead of competing in the technological field, competing in the bureaucratic field, who will give a greater kickback to any official.
It's time to change approaches, dear. For the good of the Fatherland.

I agree, we really need solar energy and it has great prospects both for the future and for the present, for example, if you introduce all this everywhere, then in the summer you can achieve huge savings, solar energy itself is very cheap, it can be used for all buildings under construction to put such elements and all this to unite in a network and ecology will be better and saving. Solar energy could occupy a huge part of the market for a long time, but oil industry and coal mining companies would not allow this unfortunately, if it weren’t for them, then I’m sure at 100% we would already drive electric cars, it’s just that these technologies are artificially slowed down by them, it’s time already remember the ecology, drive electric on our own and push oil faster abroad.

[Ross]

Joker,
That's right, the oil workers themselves are buying up all the advanced developments and the scientists themselves. Morgan did the same with Tesla. Now, in many countries, small inventors have demonstrated technologies for obtaining energy from vacuum, and this is inexhaustible energy.

[Windbreak]

demonstrated technologies for generating energy from a vacuum

with liquid or solid vacuum?

[Marine One]

From gaseous, for example. Academicians of the Russian Academy of Natural Sciences approve.

OIL WILL NEVER END. You do not believe ... then remember my statement and do not rush to smile.
Oil, like diamonds, is blown crap by a bunch of BATS.

[Joker]

There is a lot of oil, we just need new technologies for its development, BUT, electricity is better than this bullshit, all the more think Europeans will be sitting on our oil for a long time? They will make high-capacity batteries, put them in a car, make a lot of solar panels, hydroelectric power stations, you can have nuclear power plants and send us to hell. Ecology, which is the most important thing, you need to develop batteries, make electric cars and charging stations for them, build more power plants, then when the economy rises and bang, we will switch to electric cars and we will push oil purely abroad. That's better.

By the way saw a new crossover from AvtoVAZ? It will be mass-produced from 2015 of the year.

For a huge breakthrough in this area, there must be the will of the state! Not only financially supported, but also popularized environmental types of energy among the population and business!
In Germany, citizens sell surplus clean electricity to the state at prices that are two times more expensive than they can buy on the grid.
I saw in Finland a hydroelectric power station for 20 kilowatts. In Russia, to put such a hydroelectric power station ?? it will be necessary to get some 200 million permissions alone !!!

What the hell is that? New SI unit?

25% more efficient is certainly good, but it’s not clear how much is left for leaders like Sharp or Bosch? What is their specific power?

[urzul]

Found this phrase:

HCPV CPV system with a concentration ratio (surface area of ​​a Fresnel lens divided by the area of ​​one solar battery) more than 300 suns.
HCPV is the acronym for High Concentrated Photovoltaic.

Skolkovo promises to help start production of these cheap solar panels

It’s even interesting what the golf club that is now in Skolkovo now can help in production ... If you plan to cut dough, then of course it’s out of competition. It would be better if the Krasnoyarsk residents set up production.

[aksakal]

Promising development.
I read that the photoelectric effect gives only the red part of the spectrum of solar radiation. I could be wrong if anyone can fix it.
But why, then, from above on this battery does not develop a film that absorbs violet and after absorption emits the red part of the spectrum? Such a film does not consume energy - it consumes it from violet radiation. It does not increase efficiency?

[Professor]

You are mistaken. For the photoelectric effect, my avatar received the Nobel Prize. So the photon is monopenisual with what long wavelength (color) it hits the photocell, it will be converted into electricity. However, the longer the wavelength (red has more than purple), the more it carries energy. So there is no need for films, except perhaps from dust.
In this area, Germans, Americans and Japanese rule. Solar cells are made from one tricky element and Russia has a unique technology for its cheap production (by chipping it from a spraying drum), but it itself has not adjusted this production, and does not want to sell the license to others. The problem is that the patent has a statute of limitations ...

This is a mistake. Right - MONOPENISSUAL

I do not know. A synonym for monopenisualism is one thing. And what is the synonym for monopenissex?

[mamba]

Quote: professor

the photon is monopenisual with what wavelength it is (in color) on the photocell; it will be converted into electricity.

The photon may not care, but the photocell does not. For solar cells that make up a solar cell, there is such a parameter as the main absorption band. Beyond its low-frequency border, the so-called "red border of the photoelectric effect", the photon will not be converted into electricity; no internal photoelectric effect is possible in a semiconductor.
For photodetectors, there is a spectral dependence of sensitivity. And from it, as a rule, only a certain part is used - the ascending, more or less linear section.

Quote: professor

However, the longer the wavelength (red has more than purple), the more it carries energy.

On the contrary, the shorter the wavelength of a quantum of light, the greater its energy.

[wax]

The photon energy is proportional to the frequency, i.e. inversely proportional to the wavelength.

[viktor_ui]

PROFF - welcome. I can give access to one "wizard" ... if interested, then throw the answer in a personal.

[Green]

Prof. Good afternoon. Correct the mistake. The shorter the wavelength, the more energy each photon carries. Violet radiation carries more energy. Ultraviolet, even more, x-rays and then the highest-energy gamma radiation. Article lantern. The world is full of SERIAL samples with an efficiency of capture of solar energy of more than 35%, by the way Israel should also be mentioned in the leaders. And there are many interesting, but technologically unsuitable, so far for mass production of thin-film photo elements with an efficiency of more than 55%. Some crap is described in the article.

[Professor]

Prof. Good day. Correct the mistake. The shorter the wavelength, the more energy each photon carries.

Yes, I was wrong. I mixed it up, because in order to create the same illumination with a red and violet lamp, for example (I worked with LEDs and lasers), more energy must be supplied to violet. That's why I mixed it up.

By the way, Israel should also be mentioned in the leaders.

Israel is certainly a leader in solar technology, but only in solar thermal technology (mirrors heat the liquid, and it rotates the turbine), in photovoltaic Israel is no different. It is interesting that it implements its solar thermal technology in the USA, Australia and other countries, and it installs photovoltaic Chinese, American, Japanese. In general, the leader in this field (as users) is Germany.

[mamba]

Quote: professor

Well, that’s completely different. You mean the different sensitivity of the human eye to different wavelengths of the visible spectrum. Therefore, different pump currents.

[mamba]

Quote: aksakal

No. Modern semiconductor materials and structures based on them allow you to convert the entire solar spectrum into electricity.

Will not raise for the reason stated above. This is simply not necessary.

[aksakal]

- I’m not a specialist, so I agree, I’ll only note that the low efficiency of solar energy conversion is depressing and the speed of increasing this efficiency is even more stupid - from the first solar panels about -3-4% to the current almost breakthrough 28% - this still needs to be verified.

Quote: mamba

- suggested - rejected - no problem. I just looked from the wrong angle to convert the spectrum to the most effective for the photoelectric effect, that’s all.

[sq]

The main problem is not getting energy, the problem is the possibility of its accumulation and transmission over long distances.

[Professor]

Just the main problem in obtaining energy, the efficiency is still very low. It is not necessary to transport it anywhere, solar panels are on the roof of the consumer. With the accumulation of so far, it’s very expensive now lithium ...

[sapulid]

Delivered a plus, for INTELLIGENT! :)))

[mamba]

Indeed, the efficiency is not yet higher than 39% for serial photocells, and the cost of one such kilowatt hour for the European consumer is now 0,14 euros.
In the future, the efficiency will be significantly increased by creating photocells with two-sided sensitivity (up to +80% of the existing efficiency of one side), using luminescent re-emitting structures, preliminary decomposition of the solar spectrum into two or more spectral regions using multilayer film beam splitters (dichroic mirrors) with subsequent transformation of each section of the spectrum by a separate photocell, etc.

[viktor_ui]

ohhh, mistakenly set a minus (moderators ... maybe there is an opportunity to provide a one-time rollback according to the set erroneous assessment ???). Lithium in the batteries ..., zinc the roofs and window sills (the Incas used to cover the same roof with gold because they had bulk of them (gold) ..., and here the conquistadors with the sign of the cross - no luck (no knowledge , does not exempt from liability)!

[aksakal]

Quote: professor

With the accumulation of so far, it’s very expensive now lithium ...

- The increase in the price of lithium is precisely due to the increase in demand for it, just for the purpose of energy storage. So, developments are being carried out in this area. Graphene promises something there, there are prototypes of the so-called called hot batteries - where electrolytes are kept in a high temperature state. The capacity is large, the drawback is just the need to maintain high temperature.
There are silver-zinc batteries, the capacity is large, in addition, these batteries are superior to lithium in terms of power output. Those. sometimes it is required from the battery to give out a lot of power in a short time, but electrics have limitations in this part. An unsurpassed energy storage device is a banal flywheel. How much is needed and will give out. Maybe you can give up all the accumulated kinetic energy in a second, there is even a problem to "master" this energy. But silver-zinc have two big drawbacks - this is also silver is now expensive, and the second - in the process of many charge-discharge cycles, zinc build-ups grow directly into the body of electrical insulation - the so-called. the growth of zinc dendrites, in the end the insulator is pierced, the battery kirdyk. The problem has not yet been resolved, but silver-zinc, if I am not mistaken, are still used in military aviation.
And the problem of low efficiency of solar panels has not been solved either. The 39% that Mamba writes about, I will argue here, is still an unattainable value. If it were achieved, then in our southern regions of Kazakhstan we could buy Japanese hybrid cars, modify them with the installation of a solar panel, and in the summer we could forget about visiting the gas station.

[Professor]

1. A couple more methods of energy storage are practiced. In the USSR, water was pumped from one reservoir to another, now instead of a flywheel, air is pumped into cylinders, then the same air rotates the turbine.
2.

39%, which Mamba writes about, I bet here, this is still an unattainable value.

Dear snek below brought the schedule. The number in 44% is indicated there.
Single pn junction crystalline silicon devices are now approaching the theoretical limiting power efficiency of 33.7%, noted as the Shockley – Queisser limit in 1961. In the extreme, with an infinite number of layers, the corresponding limit is 86% using concentrated sunlight.

[aksakal]

- I'll read it, I'm behind the times. But 44% is really a lot, in our region in all seriousness in the summer a couple of square meters of battery with such efficiency will fully provide a house with electricity, and a car.... Maybe these are some kind of completely laboratory (non-serial) experimental samples or samples that can only be installed on large stationary batteries?

[Professor]

I was offered to put 40 squares on the roof of the house that give 10 kilowatts. It will cost about 25 tons of American rubles. I can’t make up my mind.

- a little expensive, I agree. Given your mentality, I understand twice Joke. For example, with our cost of a kW-hour in Kazakhstan being less than 10 cents, it will take an excessively long time to pay for itself. And the situation, most importantly, has not changed for many years or has hardly changed. If there had been will, we would have worked it out to the required efficiency and set up mass production, thereby lowering the price. Well, if it hasn't changed, then there are powerful forces interested in it. Look for someone who benefits
By the way, 40 squares giving only 10 kW is far from 44% efficiency. You can even count interest for the sake of. Hardly there will be 10%

You know, there was information that the States created a paint that converts solar energy into electricity. Ours, however, are treading water in the last century. Apparently, Chubais is in his element. He will do everything to satisfy the "Washington Regional Committee".

- with the wind turbine, we in Kazakhstan have finally moved from dead center. There was an invention of a Kazakh scientist, where the wind turbine perceived the wind load in a vertical position, like vertical blinds. Unlike standard wind turbines of German manufacture, here you do not need to track the direction of the wind and turn the wind turbine towards it, no matter where it is blowing from.
Experimental models are being installed at the Dzungarian Gates, where there are decent winds 365 days a year. The headache is how to get the energy from there to the consumer cities and beyond. There are no investors. If you dig a hole in the Earth, there are investors, even from overseas they will come skipping, but you still have to persuade them to do this, and they haven't persuaded you yet.

I remember still the late Jacques Yves Cousteau built a yacht with such "sails". The ship had two columns, inside which were vertical fans connected to a generator. And then the electric motor and the screw. There, too, the wind direction was unimportant.
The name of the vessel, unfortunately, I do not remember, but it looked elegant and the driving performance was magnificent.

[sir.jonn]

The most worthy advertisement for such achievements is the appearance of their results on store shelves (Yandex Market will do too). Today, through an online store, you can easily buy Chinese and other components for non-industrial solar power plants, but ours are almost non-existent and they are more expensive.
I wish the speedy introduction of new and breakthrough technologies to our electronic engineers.

Unfortunately, in China, in history lessons, they study the official map of the world. And after the lessons, as an option, they study the map of "primordial Chinese lands". Moreover, the Chinese do not need evidence-based arguments why this territory is designated as Chinese. Just tell them that the foreigners are morose - immediately there is an approving hum.

Unfortunately, this is a fairly true statement! If we let China develop for another 10-20 years, then they will not need any war.
