Abstract
Bi2S3 nanocrystals are employed in a polymer/nanocrystal solar cell as a non-toxic inorganic electron acceptor with a high absorption coefficient and a bandgap of 1.3 eV optimal for single-junction solar harnessing. The reported solar cell yields a power conversion efficiency of 0.46% in a bilayer structure and shows an internal quantum efficiency in excess of 70% as a result of efficient exciton dissociation at the interface of Bi2S3 and P3HT.
