摘要 | Two novel donor-pi-acceptor (D-pi-A) type polymers based on indacenodithiophene (IDT) and thieno[3,4-c]pyrrole-4,6-dione (TPD) with thiophene (PIDT-t-TPD) or thieno[3,2-b]thiophene (PIDT-tt-TPD) as pi-bridges were designed and synthesized. The pi-conjugated backbone length in the repeating unit of the polymer chain was varied by different p-bridges. Both polymers exhibit planar molecular structures, similar broad optical band gaps (E-g(opt)) and low-lying highest occupied molecular orbital (HOMO) energy levels. However, PIDT-tt-TPD with the more extended pi-conjugated backbone shows higher hole mobility and better miscibility with (6,6)-phenyl-C-71-butyric acid methyl ester (PC71BM). Polymer solar cells (PSCs) based on PIDT-tt-TPD: PC71BM show the highest power conversion efficiency (PCE) of 5.23% with a short-circuit current density (J(SC)) of 11.22 mA cm(-2). Considering the limited absorption of PIDT-tt-TPD (400-650 nm), the J(SC) value is very impressive. In contrast, PIDT-t-TPD:PC71BM only shows a PCE of 2.47% with a low J(SC) of 5.52 mA cm(-2). The lower J(SC) value of PIDT-t-TPD is consistent with its limited external quantum efficiency (EQE) response (lower than 40%). The present results demonstrate that extending the length of a pi-conjugated backbone by an appropriate pi-bridge in the D-A polymer improves the photovoltaic performance of PSCs. |
