Abstract (in Japanese) (See Japanese page) 
(in English) Cu2ZnSnS4 (CZTS) thin films were prepared by non-vacuum processing of sulfurizing oxhydrate precursors deposited by sol-gel method. The metal ion ratio of the sol-gel solutions for precursors was Cu poor and Zn rich, Cu/(Zn+Sn)=0.87 and Zn/Sn=1.15, and the concentration of the metal ions in the solution was 0.35M or 1.75 M. The solution of 1.75M was spin-coated after spin-coating the 0.35M solution to improve the adhesion between Mo substrate and CZTS. After the preparation of a CZTS film, a CdS buffer layer and a ZnO:Al window layer were deposited by the chemical bath deposition method and the sol-gel method, respectively, to prepare a solar cell. Thus, all the semiconductor layers were deposited under non-vacuum condition. The CZTS thin film solar cells were examined under irradiation of AM1.5 and 100 mW/cm2. As a result, the short-circuit current, open-circuit voltage, fill factor, and conversion efficiency were 2.1 mA/cm2, 0.49 V, 0.23, and 0.24%, respectively.
