The Kunitomi plant, which opened in April, began exporting 150-watt (W) copper-indium-selenium (CIS) modules last month.
Solar Frontier claims the modules have a 12.2% efficiency — higher than First Solar’s cadmium- telluride panels — and the company plans to improve that.
In testing, it set a CIS record with a 17.2%-efficient 30sq-cm sub-module, and it says it will roll those process improvements into its production lines en route to building a 14%-efficient 170W module in 2014.
