Abstract: © The Royal Society of Chemistry 2020. In this work, two new C70isomers, a and ß bis(2-(thiophen-2-yl)ethyl)-C70-fullerene mono-adducts (DTC70), were synthesized, characterized and used as electron transporting materials (ETMs) in perovskite solar cells (PSCs). Our results show that the a isomer improves both theJscand FF values of the devices, when compared to the results for the ß-isomer and to those for phenyl-C70-butyric acid methyl ester (PC71BM), used as control. Devices based ona-DTC70achieved a power conversion efficiency (PCE) of 15.9%, which is higher than that observed withPC71BM(15.1%).
