Over 25 years old. The copper indium gallium selenide design is a component of third generation solar cells. It has excellent weather resistance and a lifespan of more than 25 years. It also has many advantages such as high conversion efficiency, stable performance and high output power under low irradiation. . Third-generation solar cells are thin-film compound solar cells such as copper indium gallium selenide (Ga-doped CIS) and Si thin-film solar cells.
Academia and industry generally believe that solar cell development has entered the third generation. The first generation is monocrystalline silicon solar cells, the second generation is polycrystalline silicon, amorphous silicon and other solar cells, andThe third generation of solar cells are compound thin film solar cells such as copper indium gallium selenide (CIS is doped with Ga) and thin solar cells. Si film solar cells.
