摘      要：Organic photovoltaic devices(OPVs) using chiral cyclohexene-fused [C_(60)]-fullerene derivatives that have(l)-menthyl ester moiety have been prepared and their properties evaluated as acceptor molecules with P3 HT polymer: racemic cyclohexene-fused [C_(60)] fullenene,(RS)-(1 R,2 S,5 R)-2 a showed higher PCE(2.81%) than that of standard [C_(60)]-PCBM(2.64%) under the same analysis conditions. On the contrary, devices using chiral(R)-(1 R,2 S,5 R)-2 a and(S)-(1 R,2 S,5 R)-2 a, showed PCE as 1.08% and 1.10%, respectively. The main origin of the differences in PCE was found to be their poor Jsc values. The results indicate that the aggregation state might influence the interaction state with P3 HT and impact the results of the OPV properties, Jsc values in particular.
