The PSCs were fabricated from the blends of these maleimide-incorporated polythiophene derivatives and [6, 6]-phenyl-C61-butyric acid methyl ester (PCBM). A red shift of the maximum absorption wavelength was observed for the triphenylamine-maleimide functionalized side-chain type polythiophene derivatives SPTM41 and SPTM21 as compared with the maleimideincorporated main-chain type MPTM10. Moreover, fullwidths at half-maximum of UV-vis absorption bands of SPTM41 and SPTM21 were much larger than that of MPTM10. Therefore, the photovoltaic performances of PSCs based on the SPTM21/PCBM and SPTM41/PCBM blends were superior to those based on the MPTM10/PCBM blends. Among various fabricated materials, the greatest short-circuit current density (3.84 mAcm-2) and photoenergy conversion efficiency (0.37 %) were obtained for the SPTM21/PCBM blend-based PSC. © Springer Science+Business Media Dordrecht 2012. |
