Cu2ZnSnS4 (CZTS) is a promising material for the production of thin film photovoltaic modules. In this paper we report on the fabrication and characterization of ZnO/CdS/CZTS/Mo solar cells. The CZTS absorber was grown by sulfurization of a precursor composed of a multilayer of ZnS, Sn and Cu. The CZTS structural, compositional and electronic properties were investigated by XRD, SEM-EDS, Raman spectroscopy and conductivity and mobility measurements. Solar cells with the structure ZnO/CdS/CZTS/Mo were produced and fully characterized. The problems connected to the back contact are investigated and discussed.

Abstract
Cu2ZnSnS4 (CZTS) is a promising material for the production of thin film photovoltaic modules. In this paper we report on the fabrication and characterization of ZnO/CdS/CZTS/Mo solar cells. The CZTS absorber was grown by sulfurization of a precursor composed of a multilayer of ZnS, Sn and Cu. The CZTS structural, compositional and electronic properties were investigated by XRD, SEM-EDS, Raman spectroscopy and conductivity and mobility measurements. Solar cells with the structure ZnO/CdS/CZTS/Mo were produced and fully characterized. The problems connected to the back contact are investigated and discussed.File in questo prodotto:
