Researchers working with copper indium gallium diselenide (CIGS) solar cells reported a 20.4 percent efficiency result on flexible polymer films, a level that underscores how far high-performance thin ...

(Nanowerk News) Bifacial thin film solar cells based on copper indium gallium diselenide or CIGS can collect solar energy from both their front and their rear side – and thus potentially yield more ...

Avancis has set a new world record for a copper, indium, gallium, and selenium (CIGS) solar panel with an integrated series connection of 30 cm x 30 cm, achieving an efficiency of 20.3%. The German ...

Michael Kanellos is editor at large at CNET News.com, where he covers hardware, research and development, start-ups and the tech industry overseas. Venture capitalists are getting hooked on CIGS.

The idea is as straightforward as it is simple: If I can collect both direct sunlight as well as its reflection via the rear end of my solar cell, this should increase the yield of energy the cell ...
