欧米のベンチャーが競争の中でＣＩＧＳのトップレコードを塗り替えつつあります。ＮＲＥＬ（米国立再生エネ研）も評価で奮闘しています。
日本勢はどうでしょうか。産総研なども、自分で下手な相撲をとろうとせずに、ＮＲＥＬのように「国際的に信頼される」評価をしたらどうでしょう。
パブリックということを理解していないから、まあ無理かな。http://cleantech.com/news/5022/nrel-global-solars-cigs-15-percent-solon
NREL tests Global Solar's CIGS at 15.45% efficiency

German and U.S. firm also reaches new record of 11.7 percent efficiency for solar cell strings in production at its two facilities.
Berlin- and Tuscon, Ariz.-based Global Solar Energy announced today that tests from the U.S. Department of Energy's National Renewable Energy Lab confirmed 15.45 percent energy-conversion efficiency of the company's CIGS material.
Vice President of Sales and Marketing Tim Teich said NREL took a Post-it Note sized sample of the CIGS material from Global Solar's production roll, adding NREL's own topcoat and grid lines.
Global Solar also said today it reached a new record for peak efficiency of solar cell strings from its production lines. The company's 35-megawatt German and 40-MW U.S. factories produce the strings with efficiencies averaging more than 10 percent and with an upper range of 11.7 percent—a new high for the company, Teich said.
Global Solar's new efficiency milestones are in line with competitors. Ascent Solar Technologies said in July that NREL verified 10.4 percent efficiency of its CIGS solar modules, while HelioVolt said last year that Colorado State University confirmed it reached 12.2 percent conversion efficiency of its CIGS solar cells.
Global Solar started production in 2004. In the past two years, the company expanded from 4.2 MW to 75 MW of peak production capacity..
Global Solar expects to produce about 20 MW this year.
Teich said. "Can we get $1 per watt? Yes, as long as we have a market that is drawing the volume production."
