Zusammenfassung:The present invention discloses a preparation method for a reduced graphene-CuInS2 composite material, and belongs to the preparative field of photovoltaic materials. In allusion to the disadvantages that conventional pure reduced graphene has a poor photovoltaic performance, the invention provides a reduced graphene-CuInS2 composite material which is synthesized using CuInS2 and has a good photovoltaic performance. According to the method, the reduced graphene-CuInS2 composite material is obtained through three steps: preparation of graphene oxide (GO), preparation of reduced graphene (rGO) and preparation of the reduced graphene-CuInS2 composite material. The reduced graphene-CuInS2 composite material prepared adopting the present method has an great improved photovoltaic performance compared with the pure reduced graphene materials.
