subject: U.s. Department Of Energy Confirmed That Cigs Thin Film Solar Conversion Efficiency Of 15.7% [print this page] December 6, the world's major copper indium gallium selenide (CIGS) thin film solar cell manufacturers MiaSol announced that the U.S. Department of Energy's National Renewable Energy Laboratory has confirmed the company's CIGS conversion efficiency of thin-film batteries 15.7%. It is the commercial application of membrane components has been demonstrated in the highest conversion efficiency.
Investment Advisor in the new energy industry researcher Xiao letter that the other two compared to thin film solar cells, copper indium gallium selenide thin film solar cells have great prospects. Currently, thin film amorphous silicon thin film solar cells, including cells, cadmium telluride thin film batteries and thin film copper indium gallium selenide. Amorphous silicon thin-film batteries if prolonged exposure to bright light, photoelectric conversion stability is not high. CdTe thin-film battery is subject to scarcity of raw materials,gallium price, it is difficult large-scale use. In addition, the photoelectric conversion efficiency is difficult to improve but also restricts the amorphous silicon and cadmium telluride commercialization of the use of thin-film batteries. In recent years CIGS thin film cells increasing the conversion efficiency,gallium uses, decreased costs, its competitive advantage has been gradually reflected.
Investment Advisor in the Research Director Zhang Yan Lin noted that the CIGS thin film cells use to achieve economies of scale is a long process. On the one hand, the world need to intensify the propaganda BIPV, and an appropriate increase in the level of subsidies for photovoltaic power generation, thus increasing the population of the acceptance of BIPV. On the other hand,gallium, copper indium gallium selenide thin film battery technology needs to mature,gallium3d, so as to CIGS thin-film battery technology to provide strong support for universal access.
