Problems solved by technology

[0004] However, the existing solar cells are generally only light energy converters, which only convert solar energy into electrical energy output, and the storage of electrical energy is only an external energy storage device with a single function. Because the external device is not easy to carry, it directly limits solar energy. The development of battery miniaturization

Abstract

The invention discloses an energy-stored photovoltaic battery and a manufacturing method thereof. The energy-stored photovoltaic battery is sequentially provided with a positive electrode layer (2), a first electrolyte layer (3), a diaphragm (4), a second electrolyte layer (5) and a negative electrode layer (6) from a conductive surface of a top conductive glass substrate (1) to a conductive surface of a bottom conductive glass substrate (7). The positive electrode layer (2) is composed of carbon-rich TiO2 generated uniformly in situ. Compared with a common solar battery only used as a solar photoelectric converter, the energy-stored photovoltaic battery realizes that photoelectric conversion and electric energy storage are combined in the solar battery without accessories, thickness of the battery is greatly reduced, and development of simplification and ultra-thinning of the solar battery is facilitated.

Description

technical field [0001] The invention belongs to the technical field of energy, and relates to a solar cell and a preparation method thereof, in particular to an energy storage photovoltaic cell and a preparation method thereof. Background technique [0002] At present, with the increasingly serious energy and environmental crisis, seeking new renewable energy is becoming an urgent problem to be solved. Solar energy is inexhaustible, green and renewable, and has been widely used in industry, agriculture, military, aerospace, household appliances, and public facilities. However, due to its relatively high cost, large-scale use is restricted. economic constraints. Dye-sensitized titanium dioxide thin-film solar cells have the advantages of low cost, no environmental pollution, simple manufacturing process, and good stability, and have become the most promising alternative to silicon solar cells. [0003] The working principle of the dye-sensitized titanium dioxide thin film s...
