摘要: Alternating copolymers based on cyclopentadithiophene (CPDT) and five different electron-deficient aromatic units with reduced optical band gaps are synthesized via Suzuki coupling. All polymers show a significant photovoltaic response when mixed fullerene acceptor. The frontier orbital levels of the new designed to minimize energy losses by increasing open-circuit voltage respect gap, while maintaining high coverage absorption solar spectrum. best cells obtained for copolymer CPDT benzooxadiazole (BO) gap 1.47 eV. This cell gives short-circuit current 5.4 mA cm ―2 , an 0.78 V, fill factor 0.6, resulting in power conversion efficiency about 2.5%.
