The ink will work on silicon solar panels as well as those using alternative materials such as cadmium telluride (used by First Solar in the U.S.) or copper indium gallium selenide (used by Solar Frontier in Japan).

FORBES: A Swedish Solar Startup's Nanowires Promise To Deliver A Big Energy Boost

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.
