Hybrid (organic–inorganic) multication lead halide perovskites hold promise for a new generation of easily processable solar cells. Best performing compositions to date are multiple-cation solid alloys formamidinium (FA), methylammonium (MA), cesium, and rubidium halides which provide power conversion efficiencies up around 22%.

Organic–inorganic lead halide perovskites are a promising family of light absorbers for new generation solar cells, with reported efficiencies currently exceeding 22%. A common problem cells fabricated using these materials is that their efficiency depends on cycling history, an effect known as current–voltage (J–V) hysteresis. Potassium doping has recently emerged universal way to overcome this adverse phenomenon. While the atomistic origins J–V hysteresis still not fully understood, it...
