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

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.

CHANGZHOU, China, July 14, 2016 /PRNewswire/ -- Trina Solar Limited (NYSE: TSL) ("Trina Solar" or the "Company"), a global leader in photovoltaic ("PV") modules, solutions, and services, today announced 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.

Dr. Feng Zhiqiang, Vice President of Trina Solar and Director of the State Key Laboratory of Photovoltaic Science and Technology, commented, "We are pleased to announce efficiency achievements for both our multi-crystalline silicon PERC and DP cells that are based on our self-developed T1 wafers on a mass production basis. The improvements demonstrate our capabilities in continuously transforming lab technology into production practice as well as leveraging our advantages of vertical integration."

"Over the years, Trina Solar has built a solid foundation of independent research and has developed a complete set of proprietary advanced technologies and processes, through which we have attained a number of industry-leading breakthroughs that are outpacing our peers. Looking forward, we will continue to focus on applying laboratory technologies into mass production while endeavoring to reduce the solar manufacturing costs in pursuit of delivering low cost yet highly efficient solar products. The mission of Trina Solar remains unchanged and we are working harder than ever with a vision for the solar electricity to be as competitive as traditional fossil fuel power generation," Dr. Feng concluded.
