A PV manufacturer in the United States says it has received certification for its new solar cells which increase conversion efficiency from 10 to 12 percent.MARLBORO, Massachusetts, US, 2001-08-23 [SolarAccess.com] A PV manufacturer in the United States says it has received certification for its new solar cells which increase conversion efficiency from 10 to 12 percent. Evergreen Solar Inc. has received certifications under IEEE 1262 and IEC 61215 standards from Arizona State University Photovoltaic Testing Laboratory and from Underwriters Laboratory for a new Cedar Line(TM) series of photovoltaic modules. These certifications allow the company to market its new series around the world. The Cedar Line incorporates solar cells that are wider and have a higher conversion efficiency than those in the company’s previous products. The shift from a ribbon width of 2.2 inches to 3.2 inches represents a productivity increase of more than 40 percent in the wafer fabrication process, officials claim. Both ribbons were processed into 6 inch long wafers. “We are extremely pleased by the progress of our new plant,” says president and CEO Mark Farber. “The products provide reliable and environmentally clean electric power in global markets.” Solar applications of interest to the Massachusetts company include wireless power for remote homes, water pumping, lighting and rural electrification, as well as complete power systems for utility customers.
