| Summary: | 碩士 === 元智大學 === 先進能源碩士學位學程 === 98 === The electronic property of TiO2/CuO heterojunction thin film is better than TiO2 mix CuO thin film, and under 500nm wavelength irradiation can detect a current. Photoelectrode produced from Titanium dioxide, Titanium dioxide mix Copper(II) oxide, and Titanium dioxide/ Copper(II) oxide, were investigated and the characteristics, such as optical properties, electronic and optical conversion to electronic at electrolyte. Photoelectrode thin films were developed on ITO (Indium Tin Oxide) glass substrates by doctor-blade deposition techniques. Titanium dioxide and copper compounds were used to the main materials for slurry. Using light irradiation to activate photoelectrode, TiO2 can be a photoanode. TiO2 mix CuO, CuO, and TiO2/CuO heterojunction thin film can be a photcathode. Photoelectrode produced by TiO2 mix CuO have a large electric resistance.
