摘　　要：Abstract：The invention discloses a preparation method of a cuprous oxide-based multi-lamination heterojunction solar cell device. The cell comprises a glass substrate, a N-Na-codoped Cu2O film layer formed on one side of the glass substrate, a AgInZnS quantum dot layer formed on the N-Na-codoped Cu2O film layer, a ZnO transparent layer formed on the AgInZnS quantum dot layer, a cathode located on the ZnO transparent layer and an anode located on the N-Na-codoped Cu2O film layer. According to the method, AgInZnS quantum dots are used as a middle layer material of the ZnO-Cu2O heterojunction cell, the spectrum absorption range is widened, and light absorption and conversion can be expected to be enhanced; meanwhile, the AgInZnS quantum dots can regulate matching among energy levels of all the materials, accelerate separation of electrons and holes and improve the photoelectric conversion efficiency of the cell.
