Abstract

Zinc oxide (ZnO) as an electron transport material has been used in regular planar perovskite solar cells (PSCs). Herein, ZnO nanoparticles serve as an additive directly in perovskite active layer in order to fabricate a bulkheterojunction inverted planar PSC. The CH3NH3PbI3-xClx:ZnO bulk heterojunc...
