XsunX, Inc., an established solar energy company, has developed a breakthrough thin-film photovoltaic (TFPV) cross-industry technology to mass produce high efficiency, low cost CIGSolar cells. Our unique approach to high-speed small-area deposition bridges the gap between inexpensive thin-film and high performance silicon technologies.

Markets & Application Opportunities for Your Organization:

Solar Modules: Made with high performance, low cost CIGSolar cells, the lower cost alternative to crystalline silicon cells

Stainless Steel Substrates: Unbreakable, instantly improving yields and reducing WIP losses

Copper Indium Gallium Diselenide (abbreviated CIGS) is a thin film solar cell technology based on the copper indium diselenide (CIS) family of chalcopyrite semiconductors.

Significant advantages of CIGS over other solar cell technologies:

CIGS has achieved demonstrated laboratory conversion efficiencies of up to 20%, similar to that of conventional crystalline silicon and significantly greater than two other primary thin film technologies such as CdTe and a-Si

CIGSolar devices resist performance degradation over time and are highly stable in the field

CIGSolar is a direct band gap absorber that offers superior conversion efficiency potential allowing your solar products to continue to deliver improved performance into the future

Materials necessary for manufacture are readily available, and are less costly per watt of solar cell

Cell manufacture based on small-area deposition technology ensures rapid mass production, higher performance efficiencies, and lowered manufacturing costs.

Let XsunX help you grow your solar business with high efficiency, low cost CIGSolar cells
