Abstract

An anti-reflection layer (AR) is used in the solar cell to improve the amount of the irradiated light, resulting in the improvement of the performance of the solar cell. In this study, the zinc oxide (ZnO) AR is applied to the dye-sensitized solar cell (DSC) by using zinc nitrate solution. The conditions such as solution concentration and sintering temperature for fabricating the ZnO AR are changed to optimize the performance of the AR. As a result, the best performance is shown when the zinc nitrate solution with 100mM concentration is used and the sintering temperature is 600°C. And then, the ZnO AR formed with these optimal conditions is applied to the DSC. Consequently, a DSC with a ZnO AR had an increased current density up to 13.86mA/cm and an enhanced efficiency of 6.32%.
