How "Russian" perovskite will help reduce the cost of launching military satellites
A group of researchers at the University of Technology in the US state of Georgia presented a new method for creating surfaces that convert light energy into electricity. We are talking about the research group, which included scientists Thomas Brenner, Juan-Pablo Correa-Baena, Jordan Snaider, Ti Von, Shen Von, etc.
They propose the use of surfaces for solar cells from "impurity" perovskite. This, as noted, the authors of the study, allows us to generate flexible photovoltaic cells and light. In turn, this approach will allow covering practically any surfaces of spacecraft with a suitable layer, increasing the percentage of electricity generation and leading to the absence of the need to constantly reorient the frontal part of solar cells "to the Sun". It will also reduce the cost of transporting spacecraft to outer space.
According to its characteristics the efficiency of solar cells based on perovskite close to peers based on silicon.
The main problem was that the possibility of lasing perovskite spraying limited period of two months. However, after improving technology at the University of Georgia, as well as at the Massachusetts Institute of Technology, perovskite spraying "works" for a much longer time.

For your information: Perovskite was first discovered in Russia in 1839. It got its name in honor of the Russian statesman (minister) Count Lev Perovsky, who had a passion for collecting minerals. That is why the material is often called "Russian perovskite". The empirical formula of the material is CaTiO3. The largest deposits are in the Urals. Perovskite is also mined in the Alps in Austria and Switzerland. The first work on the use of perovskite in the solar power industry have been published in 2013 year. Now scientists are working on improving the technology, including to improve the efficiency of "battery".
The technology to stabilize the generation of electricity based on perovskite, voiced in the United States, is to add a small percentage of cesium and rubidium to the main crystal. Adding these "impurities" allows you to get electricity even from those areas of the battery, which during normal use were "dead" (in the absence of illumination).
Development of solar cells on the basis of "Russian" interested in the perovskite and the military. In particular, we are talking about the possibility of price reduction programs in orbit military satellites and their subsequent maintenance. Cheaper is possible due to the fact that the weight of the device will be smaller while maintaining the same power generation capabilities.

Perovskite solar cells have many potential advantages, because they are extremely lightweight and can be made on flexible plastic substrates. In perovskite has all opportunities to radically change the generating capacity in the absorption of light.
