Ascent Solar开发出长5m的CIGS型太阳能电池

　　美国Ascent Solar Technologies开发出了长度为5m的柔性CIGS（铜铟镓硒）型太阳能电池模块。模块宽度为32cm，重量为2kg。底板采用聚酰亚胺。开口部的发电效率为9.1％，输出功率为123W。

　　Ascent Solar将该模块定位为面向建材一体化（BIPV）太阳能电池的主要产品。利用年产能为1.5MW的卷对卷设备生产。目前正在建设中的年产能30MW的工厂预定导入生产设备。

长度为5m的CIGS型太阳能电池模块

Ascent Solar Technologies Inc., Colorado based thin-film PV module manufacturer, has successfully manufactured a 5 meter monolithic flexible thin-film solar module on a polyimide substrate. This is the largest manufactured monolithic module produced so far, according to the company. The size and efficiency of this solar module represents a breakthrough and creates emerging opportunities for the market.

The CIGS based thin-film material used for the manufacture of the module comes from the company’s unique 1.5 MW roll-to-roll manufacturing line. The produced module was encapsulated during manufacture and will be used for a 30 MW solar power plant, currently under construction. The module itself weighs about 2 kg and is capable of outputting about 123 W of power, achieveing apperture efficiency of about 9.1 percent. The newly established product dimension of 5m represents the baseline for the development of the company’s large area flexible building integrated photovoltaics (BIPV) products.
