Abstract

The invention relates to a solar cell and aims at providing an energy storage type solar cell. The energy storage type solar cell takes a non-woven fabric made from polypropylene fibers or an anion exchange membrane as a dissepiment, takes an alkaline solution as electrolyte and takes a mixture of cobalt hydroxide loaded on foamed nickel and carbon black as a positive pole; a negative pole of the energy storage type solar cell is in a pressed multi-layer structure sequentially including a conductive glass, a TiO2 layer coated on the surface of the conductive glass with a binding agent, a hydrogen storage metal (loaded on the foamed nickel)-TiO2 mixture layer and the foamed nickel from outside to inside; and the mixture loaded on the positive pole and the foamed nickel of the negative pole are respectively opposite to the dissepiment. The invention not only realizes the photoelectric conversion of solar energy, but also stores the solar energy in real time, is easy to miniaturize, has easy miniaturization and low cost without pollution and carbon emission and is environmental friendly; in addition, a solar cell power generation device is easy to miniaturize due to the intensification of a power generation function and a power storage function.

Description

technical field [0001] The invention relates to a solar cell, in particular to an energy storage type solar cell. Background technique [0002] With the development of the world economy and the improvement of people's living standards, limited natural resources such as coal, oil, and natural gas can no longer meet the needs of human development. Solar energy has incomparable advantages: clean, inexhaustible, and available all over the world. Therefore, the development and utilization of solar energy are increasing year by year. Solar cell technology is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. At present, the application of silicon-based solar cells such as monocrystalline silicon and polycrystalline silicon has entered a stage of large-scale development. However, traditional solar cells cannot store the generated electric energy, and silicon-based solar cells are expensive, which is not c...
