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. © 2023, Universiti Malaysia Perlis.
