Trina Solar Achieves Average Efficiency of 20.16% for Multi-crystalline Silicon PERC Cells

Trina Solar has announced that it has achieved an average efficiency of 20.16% for its industrially-produced P-type multi-crystalline silicon cells 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.

Both the multi-crystalline PERC cells and DP cells are fabricated on a new gen of high-performance p-type Trina-1 wafers (T1 wafers).

The company in a statement said  T1 wafers were independently developed 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 said the company.

Feng Zhiqiang, Vice President of Trina Solar , said “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.”He further added “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.“
