In recent years, many people have studied the use of nano-TiO 2 to convert light energy into electrical energy and chemical energy. With the increasing emphasis on solar power generation in the world, nano-TiO 2 has become the most commonly used material for researching photovoltaic solar-converted batteries due to its excellent nature. Weller et al. reported that the quantum-sized CdS has a sensitizing effect on the porous polycrystalline nano-TiO 2 electrode, and the photoelectric conversion rate is 6% under monochromatic light irradiation. Gratzel reported superior performance by ruthenium pyridine sensitized nano T1O 2 PEC cell under simulated sunlight, the photoelectric conversion efficiency of up to 12%, the photocurrent density of greater than 12A / cm 2. The research group directed by Professor Cai Shengmin of China has reported the combination of conductive polymer and nano-TiO 2 for solar power generation and has high photoelectric conversion efficiency.
