Abstract: Abstract: We developed bulk-heterojunction (BHJ) polymer solar cells (PSCs) by slot-die coating a poly(3-hexylthiophene):fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) composites with various solvents, such as chlorobenzene (CB), dichlorobenzene (DCB), or a CB/DCB co-solvent. To understand the effect of solvent on the uniform active layer film coating and charge carrier recombination, we characterized the coated films with UV–visible absorption spectroscopy, and analyzed the measured light intensity dependence of the cells׳ short-circuit current density and open-circuit voltage . The PSC with the active layer that was made with a CB/DCB co-solvent shows better uniform film quality and power conversion efficiency (PCE) due to its relatively small bimolecular and trap-assisted recombination. Finally, we successfully fabricated a uniform large-area PSC module from P3HT:PCBM with a CB/DCB co-solvent system, which shows a PCE of 1.73% under the condition of air mass 1.5.
