Outline of Final Research Achievements |
To increase the open-circuit voltage of inverted polymer solar cells (PSCs) and to improve the productivity of film preparation, we synthesized novel polymers consisting of benzo[1,2-b:4,5-b0]dithiophene and thieno[3,4-b]thiophene units (PTB-F), containing 4-fluorophenyl pendants as electron donor materials. We found that both the HOMO and LUMO were linearly deepened with an increasing TT-F content. Meanwhile, the solubility to chlorobenzene decreased with the increasing TT-F content. These polymers were used as electron donor materials in inverted-type PSCs. 4-Fluorophenyl pendants also influenced the morphology of the PTBFx:PC61BM blends, the crystallinity and orientation in the active layers, and hole mobility, which appear to be closely related to the photovoltaic properties. PTB-F75 bearing a moderate content of 4-fluorophenyl pendants provided superior performances with power conversion efficiency of 4.3%.
