Introduction to CdTe and CIGS Thin-Film Solar Cells

摘要

Thin-film solar cells have the advantage of low material cost. The production cost as low as USD 0.86/W has been realized and announced recently by First Solar, a company produces CdTe solar modules. CIGS is another kind of thin film product having the potential for high cell efficiency as well as the feasibility for the development of non-vacuum roll-to-roll processes with very low cost. In this article, we give an introduction to CdTe and CIGS thin-film solar cells for their material properties, device structures, and mass production technologies.
