【前沿】CIGS薄膜電池效率突破20%(德國ZSW) 已有9人參與
|
|
最近由德國太陽能和氫研究中心(ZSW)制造的CIGS薄膜電池(0.5cm2)效率達到20.1%,突破08年NREL創(chuàng)造的19.9%的轉換效率。該工藝也采用共蒸發(fā)路線,并有望獲得15%的商業(yè)化組件轉換效率。 German researchers ring 20% CIGS bell May 4, 2010 - Researchers from Germany's Centre for Solar Energy and Hydrogen Research (ZSW) are claiming a new record for thin-film solar cell efficiency, and say the mark is achievable beyond the demonstrated material (CIGS) to thin-film technology in general. The mark of 20.1%, said to be confirmed by the Fraunhofer ISE in Freiberg, Germany, surpasses the previous mark by NREL, which held the record for 16 years, ZSW claims in a statement. The 0.5cm2 area, 4μm-thick CIGS cell was produced in a lab using a modified co-evaporation process, which "in principle can be scaled up to a commercial production process," the researchers note. (The ZSW is collaborating with Würth Solar, whose first commercial CIGS line came online in 2006 and is now 30MW capacity.) Commercially available CIGS modules sport around 10%-12% efficiency, but the new CIGS technology could usher up to 15% efficiency at commercial module levels "within the next few years," according to Michael Powalla, head of ZSW's photovoltaics division. http://www.electroiq.com/index/display/photovoltaics-article-display/5663321049/articles/Photovoltaics-World/thin-film_solar_cells/cis_-cigs/2010/may/german-researchers.html |
