Abstract

original image

Hybrid poly-3-hexylthiophene (P3HT)–Sb2 S3 nanocomposite films are formed by means of an in-situ low-temperature thermal decomposition of a solution-processable antimony xanthate precursor in a polymer film. Transient optical spectroscopy and photovoltaic device studies suggest that charge separation and current generation in Sb2S3:P3HT based devices results mainly from Sb2S3 light absorption and subsequent hole-transfer from the inorganic semiconductor to the organic hole transporting material.
