Abstract:
A series of donor/acceptor carbazole copolymers comprising alternating 6,7‐diphenyl‐4,9‐bis‐(thiophen‐2‐yl)‐[1,2,5]thiadiazolo[3,4‐g] quinoxaline and 3,6‐dimethyl‐9‐alkyl‐ 9H ‐carbazole repeat units ( P1 ), or 3,6‐dimethyl‐9‐triarylamino‐ 9H ‐carbazole repeat units ( P2 ), or 9‐triarylamino‐ 9H ‐carbazole repeat units ( P3 ) has been prepared following Suzuki polymerization procedures. P3 absorbs light up to 1 200 nm and has an energy gap of 1.1 eV, while P1 and P2 have energy gaps of 1.3 and 1.25 eV, respectively. Photovoltaic cells with ITO/PEDOT:PSS/ P3 :PCBM (1:1 w/w)/Ca showed an open‐circuit voltage of 0.4 V under white light illumination, power conversion efficiency of 0.61%, and short‐circuit current of 5.2 mA · cm −2 . magnified image
