Nanosolar is one of several Silicon Valley startups that have attracted billions of dollars in venture capital to develop a thin-film technology called copper indium gallium selenide, or CIGS. Such solar cells use little expensive silicon, the main ingredient of conventional photovoltaic cells.

IBM's approach is based on a process developed by IBM Research to crank out so-called thin-film solar cells based on copper, indium, gallium and selenide.

At nearly 14%, the efficiency of the thin-film panels which are made from copper, indium, gallium and selenium (CIGS), is close to that of silicon, albeit being much cheaper to produce.
