ZnO is great interest for large-area optoelectronic devices, e.g., flat panel displays, light-emitting diodes, transparent semiconductors, and transparent conductive oxides (TCOs) etc., owing to its good optical properties. Especially, i-ZnO and TCO are one of the important layers in CZTSSe solar cells because they must transmit light to the absorber layer and having conductivity for carrier movement. Our research group confirmed that the i-ZnO thickness and TCO deposition temperature are related to each other. In this study, the PCE change of the CZTSSe solar cell was confirmed by controlling the i-ZnO thickness to 25 to 100 nm. high i-ZnO thickness was applied, the efficiency of CZTSSe solar cell tended to increase. |
