摘要

薄膜太陽電池具材料成本低之優勢，以CdTe為主要光吸收層材料的太陽電池模組其每瓦量產成本已低達0.86美元，而CIGS太陽電池有高效率的特點也兼備可開發低成本製程的可行性。本文針對CdTe和CIGS兩類薄膜太陽電池就其材料特性、元件結構、製程技術等介紹與評論，同時也可看出二者之差異與未來發展之趨勢。

並列摘要

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.
