In this paper, we fabricate the solution-processed solar cell to investigate the effect of the boiling point of the solvent additive on the performance of the polymer solar cell. We select the non-halogen solvent trimethylbenzene (TMB) as the host solvent and 2,2-(1,2-ethanediyldioxo) diethyl mercaptan (EOS) as the solvent additive to process the solar cell based on the FBT-Th4(1,4): PC71BM. The best power conversion efficiency is over 10%, which is the best result among the solar cells based on FBT-Th4(1,4): PC71BM. It should be noted that EOS can fast remove completely during the film-forming period. In order to investigate the underlying reason that the performance is improved, the TEM and AFM measurement are carried on. At last, we research the air stability and thermal stability of the solar cell processed with the new solvent additive.
