First Solar Marks Thin-Film Efficiency And Durability Milestones


First Solar Inc. has claimed another set of performance achievements for its cadmium-telluride (CdTe) photovoltaic research cells.

The Newport Corp.'s Technology and Applications Center PV Lab has recorded a conversion efficiency of 21.5% for First Solar's CdTe test cells. First Solar says the research cell was constructed at its Perrysburg, Ohio, facility using processes and materials suitable for commercial-scale manufacturing.

The company has said its technology road map for thin-film technology remains a foundation of its future as a PV manufacturer and developer of solar power projects.

First Solar also announced that its commercial modules have passed Atlas 25+ certification following a series of long-term combined-stress environmental exposure tests conducted by Atlas Material Testing Technology. The company says formal certification documentation will be issued by SGS.

‘Our latest research cell-efficiency record is a result of continued learning in the material science and device physics of CdTe solar cells,’ says Raffi Garabedian, First Solar's chief technology officer. ‘Our work is not done in isolation but is, in part, a result of the many fruitful collaborations we have with academia, national labs and our industrial partners, most notably GE Global Research.’
