Abstract
A new donor‐acceptor conjugated copolymer (PDTPyDPP), comprising 2,7‐di‐2‐thienyl‐4,5,9,10‐tetrakis(hexyloxy)pyrene as a donor and diketopyrrolopyrrole (DPP) as an acceptor, was synthesized. PDTPyDPP showed good solubility in common organic solvents, broad visible absorption from 300 to 900 nm, and a moderate hole mobility up to 6.3 × 10−3 cm2 V−1 s−1. The power conversion efficiency of the photovoltaic device based on the PDTPyDPP/PC71BM photoactive layer reached 4.43% with 0.66 V of open‐circuit voltage (Voc), 10.52 mA cm−2 of short‐circuit current (Jsc) and 64.11% of fill factor
