Types of solar thin-film batteries

Solar thin-film batteries can be divided into: silicon-based thin-film solar cells, inorganic compound thin-film solar cells, inorganic compound thin-film solar cells, and dye-sensitized thin-film solar cells, and each type of solar thin-film battery has a specific type .

Silicon-based thin-film solar cells include amorphous silicon thin-film solar cells, polycrystalline silicon thin-film solar cells and microcrystalline silicon solar cells.

Amorphous silicon thin film solar cell is a thin film solar cell based on amorphous silicon compound.

The polycrystalline silicon thin-film solar cell combines the advantages of high conversion efficiency and long life of the monocrystalline silicon cell, and the relatively simplified preparation process of the material of the amorphous silicon thin-film battery.

Microcrystalline silicon solar cell is a kind of mixed phase disordered semiconductor material between amorphous silicon and single crystal silicon. It is a kind of solar cell delayed by crystalline silicon particles embedded in tens to hundreds of nanometers. In amorphous silicon film.

Inorganic compound thin film solar cells include cadmium telluride (CdTe) thin film solar cells, copper indium selenium CIS (CIGS) thin film solar cells, and gallium arsenide (GaAs) thin film solar cells.
Cadmium telluride (CdTe) thin film solar cell, which is a thin film solar cell based on the heterojunction of p-type CdTe and n-type CdS.

Copper indium selenium CIS (CIGS) thin-film solar cells are deposited on glass or other inexpensive substrates with several layers of metal compound semiconductor thin films. The total thickness of the thin film is about 2 to 3 microns, which uses sunlight to generate electricity.

Gallium arsenide (GaAs) thin-film solar cells GaAs belong to group III-V compound semiconductor materials, and their energy gap is more suitable for matching with the solar spectrum and can withstand high temperatures. Compared with silicon solar cells, GaAs solar cells have better performance.

Inorganic compound thin-film solar cells mainly include single-layer Schottky cells, double-layer P-n heterojunction cells, and bulk-phase heterojunction cells with P-type and N-type semiconductor network interpenetrating structures.
Dye-sensitized thin-film solar cells are actually a new type of light spot chemical battery developed to imitate the principle of photosynthesis.

Dye-sensitized TiO2 thin-film solar cell, using dye-sensitized bipyridine ruthenium (Ⅱ) complex and nanoporous TiO2 thin film to prepare dye-sensitized TiO2 solar cell.

A dye-sensitized ZnO thin-film solar cell is a thin-film solar cell in which Al doping preferentially grows and crystallizes the ZnO crystal plane.

These are the categories of solar thin-film batteries. More high-quality new solar thin-film batteries are under development.
