摘要	In this work, ethyl benzenecarboxylate (EB) was creatively selected as the additive in a blend of poly(3-hexylthiophene)/phenyl-C71-butyric acid methyl ester (P3HT/PC71BM) in non-halogenated solvent toluene (TL). With the optimized incorporating concentration of EB (i.e. 2 vol%) in toluene, a great power conversion efficiency (PCE) enhancement of 4.11% was achieved without thermal annealing, whereas a maximum PCE of 4.82% with thermal annealing was achieved under the same conditions. According to our systematic characterization results, we could conclude that we successfully regulated the microstructures, including phase separation, the domain sizes of P3HT or PC71BM and the crystallinity of P3HT by incorporating 2 vol% EB in TL solution. The effectiveness of EB as a TL additive in P3HT/PC71BM can be interpreted based on its Hansen solubility parameters (HSPs) and its high boiling point.
