摘要：

In this paper, we synthesized a novel type II cuprous sulfide (Cu2S)-indium sulfide (In2S3) heterostructure nanocrystals with matchstick-like morphology in pure dodecanethiol. The photovoltaic properties of the heterostructure nanocrystals were investigated based on the blends of the nanocrystals and poly(2-methoxy-5-(2'-ethylhexoxy)-p-phenylenevinylene) (MEH-PPV). In comparison with the photovoltaic properties of the blends of Cu2S or In2S3 nanocrystals alone and MEH-PPV, the power conversion efficiency of the hybrid device based on blend of Cu2S-In2S3 and MEH-PPV is enhanced by similar to 3-5 times. This improvement is consistent with the improved exciton dissociation or separation and better charge transport abilities in type II heterostructure nanocrystals.
