The photo-induced charge transfer and optoelectronic efficiency of the solar cells correlated to the morphology and the structure of P3HT:C60 blend was studied by means of photoluminescence and electron spin resonance (ESR). The occurrence of photo-induced charge transfer, well-known for blends of P3HT with fullerenes, was evidenced in blends of P3HT:C60 (1:1 wt ratio) by a strong partially quenching of the P3HT luminescence. The ESR measurements allowed one to quantify the charge transfer between P3HT and C60, which resulted in positive P3HT polarons. Wide-angle X-ray scattering (WAXS) and UV–vis spectroscopy showed that an inclusion of a C60 fullerene in the P3HT matrix lead to lower peak intensities and dark Debye rings and a blue shift on the p–p* interband transition of the P3HT as well as a reduction in the absorption coefficient. Selected area electron diffraction patterns of a well-ordered sample of P3HT exhibit distinct diffraction rings indicating that the P3HT forms a polycrystalline film. The large-scale phase separation of P3HT and C60 resulted from large C60 agglomerations during spin coating lead to a low power conversion efficiency of 0.2 9 10-4%. |
