The Enhancement Light Absorption of ZnO-TiO2 Nanocomposite as Photoanode
INTERNATIONAL JOURNAL OF NANOELECTRONICS AND MATERIALS(2023)
摘要
ZnO nanomaterial in Dye Sensitized Solar cells (DSSC) has the disadvantage of low efficiency. The purpose of this study was to improve the DSSC efficiency of the ZnO photoanode. ZnO-TiO2 nanocomposites are used as photoanodes that can improve light absorption. ZnO-TiO2 nanocomposites can increase the performance efficiency of the solar cell compared to ZnO Pristine. This is due to the reduced recombination between ZnO/electrolyte and the increased lifetime of electrons because of the presence of electrons trapped in TiO2. The most optimal sample from this study was found in ZnO-TiO2 nanocomposite with a volume concentration ratio (85%-15%) because the efficiency DSSC increases almost 2 times.
