Trina Solar Ltd., a provider of photovoltaic modules, solutions and services, says it has achieved an average efficiency of 20.16% for its industrially produced P-type multicrystalline silicon cells (156 x 156 mm2) with passivated emitter and rear cell (PERC) technology and also achieved an average efficiency of 18.7% for its multicrystalline silicon P-type double print (DP) cells (156 x 156 mm2) that were mass produced for commercial shipment.

According to Trina, both the multicrystalline PERC cells and DP cells are fabricated on a new generation of high-performance P-type Trina-1 (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.

Trina says the multicrystalline silicon PERC cells are built on the advanced rear passivation technology that integrates the Reactive Ion Etching process for better light trapping. Modules (60 pcs cells) equipped with these high-efficiency multicrystalline silicon PERC cells have managed to produce an output of 286 W.

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 multicrystalline 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.”
