  • Abstract
    Cu2ZnSnS4 (CZTS) thin film solar cells were successfully fabricated on Corning® Willow® Glass substrates coated with a Molybdenum (Mo) back contact. The CZTS thin films were deposited by using magnetron sputtering followed by annealing in sulfur vapor for 30 minutes. The best conversion efficiency achieved of the flexible CZTS solar cell was 3.08%, with an active area of 0.45cm2. The conversion efficiency was reduced by 20% when the cell was bent to a 50mm radius. The degradation is caused by higher series resistance, which can be due to the degradation of the TCO layer and the damage in the CZTS/Mo interface.
