Lead Halide Perovskite may Lead to More Efficient Solar Cells Written by AZoMJan 22 2021 Among the group of materials called perovskites, one of the most fascinating is a material that is capable of changing solar light to electricity as efficiently as present-day silicon solar cells available in the market. This material could also be produced much more easily and cost-effectively. Scientists at SLAC National Accelerator Laboratory and Stanford University discovered that squeezing a promising lead halide material in a diamond anvil cell (left) produces a so-called “black perovskite” (right) that's stable enough for solar power applications.
