摘要
Aiming to develop the solar cell free from the environmental contaminants, a thin film type solar cell was produced by using Cu2ZnSnS4 (CZTS). CZTS thin films could be successfully formed by the vapor phase sulfurization of the precursors prepared by vacuum evaporation. Instead of CdSO4, CdI2, was used as the Cd-source in the preparation of the CdS buffer layer by chemical-bath-deposition technique. This buffer layer increased both the value of FF and the conversion efficiency from 0.4 to 0.6 and from 2.62 % to 4.25 % respectively. In order to examine the effect of addition of Na, the CZTS-based solar cell with Na2S/Mo/SiO2/SLG substrate was produced. The present study obtained the value of FF and the conversion efficiency as 0.6 and 5.45 % respectively, which are the best records in all many studies on CZTS.
