In purely statistical terms, the growth rate of thin film solar cell market touched a whopping 60 percent benchmark from 2002 to 2007. Suffice it to say, such kinds of advanced CIGS solar cells do account for a crucial commercial chunk of renewable energy. But the predicament lies with their relatively high-cost of manufacturing and usage, partly due to the technology’s utilization of expensive rare earth materials like Gallium and Indium. Fortunately, scientists are looking forth to a solution that can significantly alleviate this high cost factor. Midsummer, a company dealing with cost effective production of CIGS solar cells, has collaborated with Professor Christian Ekberg and PhD-student Anna Gustafsson (from Swedish Chalmers University of Technology) to develop a special procedure that can effectively recover the leftover rare metals after a conventional manufacturing process (of solar cells).
