Trina Solar, a global provider of solar modules, solutions, and services, 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. These results come on the heels of Trina Solar’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.”
