Perovskite solar cells with ZnS as electron transport layer

Abstract

This work demonstrates the application of ZnS thin layers and the doped layers with ZnS in the perovskite solar cells. Electron transport layer has been used in three different forms. For solar cells with a single layer of ZnS – a power conversion efficiency of about 1.64 % was obtained. By using PC61BM fullerene layer doped with ZnS, devices with power conversion efficiency of about 3.98% were obtained, and by the application of two different layers, one of PC61BM and second of ZnS, solar cells with a maximum power conversion efficiency of about 5.76% were obtained.
