CIGS (Copper Indium Gallium Selenide) is consisting of four copper (Cu), indium (In), gallium (Ga) and selenide (Se). CIGS forms different phases under different temperatures and in various composition ratios. The chalcopyrite structure is the main CIGS application. Its semiconductor and light-absorbing characteristics change along with different ratios of the consisting elements. CIGS can absorb a wide range of the light spectrum. Its reliability and the conversion efficiency to convert light into electricity is the highest among all kinds of thin-film solar cells
RITEK Technology produces CIGS modules with integrated processes from cells to module assembly. We are able to manufacture larger-size modules that standard size, in order to lower material and production costs. This approach also avoids the issue concerning unsteady material supplies. RITEK’s CIGS modules have higher light absorption efficiency and accumulated energy generation compared to crystalline modules. Meanwhile, our CIGS modules have a longer lifespan. They show unlimited potential in a wide range of applications.
