Problems solved by technology

However, because the electrolyte solution is generally acidic, it will corrode the nano-semiconductor film and affect the working stability of the dye-sensitized solar cell; in addition, TiO2 particles are used as the nano-semiconductor film in the general dye-sensitized solar cell. The large specific surface area and defects of the particle film can easily cause the recombination of electrons, thereby reducing the photoelectric conversion efficiency

Description

technical field [0001] The present application relates to the field of solar cells, in particular to a solar cell. Background technique [0002] Energy is the basis of all production activities in human society. With the development of modern economy, human demand for energy is becoming increasingly intense. The reserves of traditional energy are limited, and its content is becoming more and more depleted, and because traditional energy produces a large amount of toxic and harmful gases, solids, etc. during the utilization process, it has become the chief culprit of increasingly serious environmental pollution. Based on this, the development of new energy and renewable energy is the focus of research in the 21st century. Among them, solar energy resources depend on sunlight and are an inexhaustible clean energy source. In recent years, the solar photovoltaic industry has developed rapidly, and the development of cheap and efficient solar cells has become a research hotspot...
