Abstract
Recent developments in perovskite solar cells have achieved efficiency around 22%. However, degradation of perovskite material on contact with moisture is still an issue. In this study, inverted planar perovskite solar cells via solution processing at low temperature are prepared with different electron transport layers. The zinc oxide and aluminum doped zinc oxide are used as electron selective layer between PCBM and back contact. The metal oxides act as protective layer resulting in increased stability against moisture. Furthermore, this interlayer improves charge transfer and collection, leading to significantly increased short circuit current density and fill factor. The champion cell with power conversion efficiency 12.01% is obtained for doped zinc oxide interlayer obtained under 1-sun condition.
