PFN (Poly [(9,9-bis(3'-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9–dihexylfluorene)]) with several types of organic acid derivatives as the cathode buffer layer for polymer solar cells |

The effect of acid additives such as Acetic Acid (AA), 4-trifluoromethyl benzoic acid (CF3BA), trifluoroacetic acid (CF3AA), and 4-toluene sulfonic acid (TsOH) in PFN on device performance were investigated, we fabricated and tested inverted PSCs that use a blend of PTB7-Th and PC71BM as the active layer and PFN with different amounts and types of acid derivatives as the CBL. The optimum amount of acid derivatives was found to be 1.0 eq. for all the devices based on ZnO/PFN. The FF and PCEs of the devices followed the trend of the acid dissociation constant of acid derivatives. We discovered that the most effective acid derivative was TsOH in this study. The devices based on PFN with acid derivatives exhibited reduced trap-assisted recombination and interfacial bimolecular recombination. Notably, the reduced trap-assisted recombination of the devices agrees well with the trend of the PCEs of PSCs and follows the trend of the acid dissociation constant of acid derivatives. |
