Deposition of CuInS₂ Absorber Layer for a Prototype Solar CellFang, Yizhou; Jiang, Feng; Muscat, Anthony J.; Chemical and Environmental Engineering (2011-11-04)A copper indium disulfide (CuInS₂ or CIS) film could potentially be used as the absorber layer in a solar cell that converts solar energy into electricity. CuInS₂ was chosen to lower the cost and environmental impact of manufacturing as an alternate to Si solar cells. The objective of this project is to deposit a uniform CuInS₂ film with a thickness of 2-3 μm. Both spin-coating and painting methods were compared. The substrate, oxidation method, and sulfurization temperature were varied and characterized.
