Control of toxic gas release during the production of copper-indium-diselenide photovoltaic cells
Toxic gas control systems will be needed to treat both routine and accidental H/sub 2/Se and H/sub 2/S emissions from manufacturing facilities producing CuInSe/sub 2/ photovoltaic cells. In this study, routine and accidental environmental control options were evaluated for a manufacturing plant with an annual production of cells capable of generating 10 MWp. A routine emissions treatment facility was designed which uses a venture scrubber, a packed-bed scrubber, and a carbon adsorption bed to reduce emissions to allowable limits. This facility incrementally increases the cost of manufacturing CuInSe/sub 2/ photovoltaic cells by 0.60 cents/Wp. Two alternative systems were designed to handle an accidental release: a packed-bed scrubber/carbon adsorption bed, and a containment scheme followed by carbon adsorption. The incremental costs of manufacturing for these release systems are 0.91 cents/Wp and 1.25 cents/Wp, respectively.
