Fabrication of TiO2-ZrO2 Binary Oxide Electrode with Natural Dye (Rose) for Dye Sensitized Solar Cell Application
TiO2-ZrO2 fine binary oxide was firstly prepared by mechanochemical milling process to be homogeneous binary oxide powder. TiO2-ZrO2 paste was deposited onto microscopic glass slide by rolling. It was immersed in the Rose solution at different pH levels and annealed at 100°C for 2h. Carbon catalyst obtained from soot and HCl was coated onto another glass slide and it was used as counter electrode. Two glass slides were offset and two binder clips were used to hold the electrodes together. Photovoltaic properties of TiO2-ZrO2 cells were measured at different pH levels and it was expected to utilize the dye sensitized solar cells application. The highest efficiency (0.23%) of the dye sensitize solar cell was found to be rose extract at pH level 4.1. The cell exhibited the potential to be a low-cost photovoltaic option.
