A team of researchers from the National University of Science and Technology (MISIS) in Moscow, in cooperation with colleagues from the University of Texas at Dallas, have developed a flexible solar battery which is said to be at least three times cheaper than its silicon analogues.
The scientists created a perovskite-based thin-filmed photoelectric cell, which made it possible to create an advanced solar battery. According to the tram, the achievement was made possible by the fact that the selected perovskites can convert solar energy radiation into electric energy with a performance coefficient of more than 15%, and with a planned rate of 20%.
Perovskites are much cheaper than currently popular materials, and facing mass production these price differences are most likely to be increased by at least six times, scientists said, also pointing to toxic production of the silicon solar batteries.
