Three types of 2,5-diarylfulleropyrrolidine derivatives, i.e., 2,5-diphenyl, 2,5-di(thiophen-2-yl), and 2,5-di(thiophen-3-yl)fulleropyrrolidines were used as acceptor molecules with P3HT of OPV devices using two types of ITO electrodes. Their PCE depended on both the stereochemistry and nature of the two aryl substituents at the 2,5-positions of the pyrrolidine ring: the PCE of the devices using trans-diphenyl or both cis- and trans-di(thiophen-3-yl) compounds were significantly lowered by using an ITO electrode with PEDOT:PSS, while the cis-diphenyl isomer was not influenced by PSS. Furthermore, both cis- and trans-2,5-di(thiophen-2-yl)fulleropyrrolidine displayed high PCE using PEDOT:PSS.
