Abstract

High efficiency organic and hybrid solar cells create demand for novel electron acceptor materials that possess appropriate energetic band levels and bandgap for efficient solar energy harnessing. We present hybrid bulk heterojunction devices based on P3HT and bismuth sulfide nanocrystals, a semiconductor based on environmentally friendly compounds, with a power conversion efficiency of 1% and NIR sensitization at 700 nm of 30%, among the highest ever reported for P3HT.
