Trina Solar Achieves Average Efficiency of 20.16% for Industrially-Produced Multi-crystalline Silicon PERC Cells and 18.7% for Commercially-Produced Multi-crystalline Silicon DP Cells

CHANGZHOU, China --- Trina Solar Limited announces that it has achieved an average efficiency of 20.16% for its industrially-produced P-type multi-crystalline silicon cells (156 x 156 mm2) with passivated emitter and rear cell ("PERC") technology, and an average efficiency of 18.7% for its multi-crystalline silicon P-type double print ("DP") cells (156 x 156mm2) that were mass produced for commercial shipment. The results, tested by the Company, further solidify Trina Solar's leading position in cutting-edge technology for the mass production of high efficiency crystalline silicon solar products, following the Company's recent efficiency breakthrough in mono-crystalline silicon PERC cell production.

Both the multi-crystalline PERC cells and DP cells are fabricated on a new generation of high-performance p-type Trina-1 wafers (T1 wafers). The T1 wafers were independently developed by Trina Solar based on the technologies that include homogeneous nucleation and black edge free, as well as optimized technical processes, proving quality and performance assurance for the production of cells. The multi-crystalline silicon PERC cells are built on the advanced rear passivation technology that integrates the Reactive Ion Etching (RIE) process for better light trapping. Modules (60pcs cells) equipped with these high efficiency multi-crystalline silicon PERC cells have managed to produce output of 286W.
