Abstract

The experimental results obtained by applying PEDOT-PSS as a hole transport layer and PC61BM as a electron transport layer in perovskite solar cells with inverted planar architecture are presented in the work. These devices have reached a maximum power conversion efficiency (PCE) of about 19.27%. Solar cells in which bulk heterojunction was prepared from perovskite (CH3NH3PbI3) doped with PC61BM have registered a maximum PCE of approximately 23.59 %. Keywords: perovskite, PEDOT-PSS, PC61BM, current density, tension.
