ZSW公司太阳能电池片效率创纪录，达到20.3%转化效率

ＺＳＷ（Centre for Solar Energy and Hydrogen Research）公司刷新了薄膜电池片转化记录，达到了20.3%的转化效率。超过了之前四月份刷新的20.1%转化效率。之前的转化效率已经超过了美国国家可再生能源实验室之前2008年三月份的19。9%的效率。
专家说，在接下来的几年，低价位的CIGS薄膜太阳能组件将会上涨11%到15%。与08年相比，薄膜太阳能电站的薄膜太阳能组件份额将会到2012年增长一倍，达到30%。

Scientists at the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (Centre for Solar Energy and Hydrogen Research, ZSW) in Stuttgart, Germany have raised their thin-film solar cell efficiency record to 20.3%. ZSW’s prior record of 20.1% (achieved in April) had surpassed the US Department of Energy’s National Renewable Energy Laboratory (NREL), which had held the record for the previous 16 years (latterly 19.9%, achieved in March 2008).
ZSW’s latest record copper indium gallium di-selenide (CIGS) thin-film solar cells shrink the efficiency advantage of multi-crystalline solar cells (still dominating the market) to just 0.1%. The increased efficiency should significantly improve the cost-effectiveness of CIGS thin-film photovoltaics over the medium term, it is claimed.
Experts reckon that, within the next years, the efficiency of the relatively low-priced CIGS thin-film solar modules will rise from about 11% to about 15%. Compared to 2008, the market share of thin-film power plants is expected to double by 2012, reaching about 30%.
Together with industrial partner Würth Solar, ZSW has developed its CIGS thin-film solar module technology to enable industrial production. In 2006, Würth launched what is claimed to be the world’s first mass production of CIGS solar modules (in Schwäbisch Hall, Germany).
