Perovskites and Perovskite Solar Cells: An Introduction – Ossila

An approximation of current-voltage hysteresis often encountered in perovskite solar cells. To enable a truly low cost-per-watt, perovskite solar cells need to have achieved the much-heralded trio of high efficiency, long lifetimes, and low manufacturing costs.

Perovskite solar cell - Wikipedia

The name 'perovskite solar cell' is derived from the ABX 3 crystal structure of the absorber materials, which is referred to as perovskite structure.The most commonly studied perovskite absorber is methylammonium lead trihalide (CH 3 NH 3 PbX 3, where X is a halogen atom such as iodine, bromine or chlorine), with an optical bandgap between 1.5 and 2.3 eV depending on halide content.
