abstract = "Four new alternating copolymers, P(CPD-T-DPPD), P(CPD-Se-DPPD), P(CPD-T-BDPPD) and P(CPD-Se-BDPPD), containing electron rich cyclopentadithiophene (CPD) and four different pyrrolo[3,4-c]pyrrole-1,3-dione (DPPD) derivatives (T-DPPD, Se-DPPD, T-BDPPD and Se-BDPPD) were prepared using
Stille polymerization. The estimated optical band (Eg
) gaps of the copolymers were 1.96 eV, 1.88 eV, 2.00 eV and 1.92 eV, respectively. The determined highest occupied molecular orbital (HOMO)/lowest unoccupied molecular orbital (LUMO) energy levels of the copolymers were
-5.14 eV/-3.18 eV, -5.14 eV/-3.26 eV, -5.24 eV/-3.24 eV, and -5.24 eV/-3.32 eV, respectively. The polymer solar cells (PSCs) prepared with the configuration of ITO/PEDOT:PSS/copolymer:PC70BM/Al exhibited a maximum power conversion efficiency (PCE) of 0.63%, 1.01%, 0.18%,
and 0.40%, respectively.",
