Spray-cast multilayer perovskite solar cells with an active-area of 1.5 cm2

Spray-cast multilayer perovskite solar cells with an active-area of 1.5 cm2

Abstract We utilise spray-coating under ambient conditions to sequentially deposit compact-TiO2, mesoporous-TiO2, CH3NH3PbI(3−x)Clx perovskite and doped spiro-OMeTAD layers, creating a mesoporous standard architecture perovskite solar cell (PSC). The devices created had an average power conversion e...
