Abstract

In this study, Cu₂ZnSnS₄ (CZTS)-type thin film solar cells composed of abundant materials have been developed. CZTS is a promising material as an absorber in thin film solar cells because of a suitable band gap energy of around 1.5 eV and a large absorption coefficient of more than 10⁴ cm^-1. The main objectives of this study are to fabricate high-quality CZTS thin films, improve reproducibility using an in-line-type apparatus introduced in the fiscal year 2004, and fabricate high-efficiency CZTS-type thin-film solar cells. In our experiments, various parameters in precursor fabrication and sulfurization have been optimized. We achieved a maximum conversion efficiency of 6.77 %, which is the best data obtained in this material system.
