Trina Solar develops high-efficiency square monocrystalline PV cell using proprietary process

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.

    Now that the PV industry has unquestionably entered a new growth phase, all eyes are on which technologies will win through into the mainstream of PV manufacturing. PERC, n-type, p-type bifacial, heterojunction – all have become familiar terms in the ever-growing constellation of solar cell technologies. The question is which will offer manufacturers what they are looking for in improving efficiencies and cutting costs.

    Although the past few years have proved extremely testing for PV equipment manufacturers, falling module prices have driven solar end-market demand to previously unseen levels. That demand is now starting to be felt by manufacturers, to the extent that leading companies are starting to talk about serious capacity expansions later this year and into 2015. This means that the next 12 months will be a critical period if companies throughout the supply chain are to take full advantage of the PV industry’s next growth phase.
