Duebendorf, Switzerland-based Flisom’s CEO Anil Sethi released new details that his company accomplished a world record last week with its copper indium gallium selenide (CIGS) solar cells, boasting more than 16 percent conversion efficiency.

It’s one thing to do it in the lab, he told the Cleantech Group yesterday. It’s a completely different story to scale that up and still achieve the same efficiencies. But that’s what it appears the Mumbai-based Tata Group is paying Flisom to do.
