The PININEBBTMBI was used as the electron donor for the PSCs (ITO / PEDOT:PSS / polymer:PC71BM(1:4) /TiOx / Al). The unique structure of PININE, incorporating the vinylene unit with bicyclic [2.2.0] system, can overcome the basic degradation problem of the common type of vinylene units in PPV series1. The solar cells made from conjugated PININEs with benzimidazole and bithiophene units, which are new conjugated polymers for the application in polymer solar cells (PSCs), exhibit high PCEs even in basic PSC device structure. The absorption spectra of PININEDTMBI with thiophene units exhibit two maximum peaks at about 418 and 637 nm in solution. The solutions of PININEBBTMBI show two absorption peaks at about 438 and 634 nm which is red-shifted about 20 nm as compared to PININEDTMBI caused by the introduction of bithiophene units. The best solar cell performance obtained has a layered structure of ITO / PEDOT:PSS / PININEBBTMBI:PC71BM(1:4) / Al. Under white light illumination (AM 1.5 G, 100 mW/cm2), the obtained Jsc is 6.66 mA/cm2, Voc is 0.78 V, FF is 41%, and PCE is 2.11%.
