In this study, the stabilities and conversion efficiencies of perovskite solar cells including cesium (Cs) or formamidinium (FA) at the CH₃NH₃ site were investigated. The additive effects on the photovoltaic properties and crystalline structures were investigated via current–voltage measurements, X-...
