The preparation of Ag2ZnSnS4 homojunction solar cells

In this work, an Ag2ZnSnS4 (AZTS) homojunction film was obtained by the one-time introduction of sulfur on a laminated structure precursor film. Furthermore, this homojunction film was incorporated in the solar cell with a structure of Mo/AZTS /i-ZnO/ITO and an efficiency of 0.87% was achieved. This is the first report on the fabricated quaternary semiconductor homojunction solar cells. This work provides a new idea and method for the fabrication of thin film solar cells.
