Outline of Final Research Achievements |
ZnO/Cu2O thin film solar cells fabricated by aqueous solution processes, involving no vacuum and no high-temperature processes have attracted increasing attention as low-cost environmental solar cells. In this study, the introduction of buffer layer and the control of electrical properties of the oxide layer have been examined to improve the conversion efficiency. Furthermore, we have studied the fablication of flexible ZnO/Cu2O thin film solar cells that can be expected to be more versatile and lightweight. We have achieved conversion efficiencies comparable to conventional ZnO/Cu2O thin film solar cells using glass substrates.
