摘要
A novel BDT-based conjugated polymer, PBDTTT-S-TEG, and a series of new fullerene derivatives were designed, synthesized and applied to green solvent processable polymer solar cells. By rationally screening processing solvents, a PCE of 4.50% was firstly achieved with definitely low toxic, non-halogenated and safe solvent fabrication, which is almost identical to that processed with o-dichlorobenzene.
