Trina Solar develops high-efficiency square monocrystalline PV cell using proprietary process
By Tom Cheyney in PV-tech, February 10 2010
Trina Solar has developed a square monocrystalline-silicon cell with enhanced power output utilizing a proprietary improved photovoltaic cell manufacturing process. Using specially designed metallization and passivation techniques, the company says that the advanced cell structure should significantly boost cell conversion efficiency, achieving up to 18.8% in test laboratory production.
This technology is also expected to improve module output due to increased light absorbing surface area of the square-shaped cell, according to Trina.
"We are excited to announce this breakthrough in monocrystalline cell efficiency, which demonstrates the competence of our R&D team and the centrality of product development at Trina Solar," said Jifan Gao, chairman/CEO. "Trina Solar will continue to advance its extensive R&D program, aiming to develop solar cell conversion efficiencies of more than 20% over the coming two years."
Additional details about the cell architecture and the process technology were not disclosed by the vertically integrated Chinese solar manufacturing company, nor did it reveal when it expects to have the new cell running in volume production.
Trina, which will announce its fourth-quarter and fiscal year-end results for 2009 on Feb.24, has said it will have between 850 and 950MW of cell manufacturing capacity online by the end of 2010.
