Hybrid poly‐3‐hexylthiophene (P3HT)–Sb 2 S 3 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 Sb 2 S 3 :P3HT based devices results mainly from Sb 2 S 3 light absorption and subsequent hole‐transfer from the inorganic semiconductor to the organic hole transporting material.
