U.S. Department of Energy’s National Renewable Energy Laboratory has
claimed a new world record for copper indium gallium diselenide (<ACRONYM title="Copper Indium Gallium Selenide">CIGS</ACRONYM>)
thin-film solar cell conversion efficiency of 19.9 percent. In 1994,
NREL researchers had touted <ACRONYM title="Copper Indium Gallium Selenide">CIGS</ACRONYM> cell efficiencies of only 11 percent.
The conversion efficiency for <ACRONYM title="Copper Indium Gallium Selenide">CIGS</ACRONYM> is now close to that of
multicrystalline silicon-based solar cells, according to NREL.

“This is an important milestone,” said NREL Senior Scientist Miguel Contreras. “The thin film people have always looked for matching silicon in performance, and we are reaching that goal.”</DIV></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.pv-tech.org/r_and_d/article/nrel_boosts_cigs_thin_film_solar_cell_efficiency_to_record_199_percent"><DIV>
NREL researchers said that the new efficiency levels were achieved by improvements in the quality of the thin-film materials applied to the substrate. Thin-film cells require less energy to make and can be fabricated by a variety of processes, NREL said.</DIV></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/840BD18A-CFCA-430A-B0BE-EBE1A7189F5C/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
