Trina Solar’s State Key Laboratory of Photovoltaic Science and Technology (SKL) has announced that its proprietary Vertex high-efficiency p-type monocrystalline silicon module, based on 66 pieces of 210 mm x 210 mm high-efficiency PERC cells, has achieved a record aperture module efficiency of 23.03% for larger-area industrial silicon p-type modules.
This has been independently confirmed by third-party certification laboratories by both TÜV Rheinland and TÜV Nord with identical efficiency result.
The researchers in the SKL developed a new multi-busbar (MBB) technology to improve optical shading, and developed a new hybrid soldering technology to minimize the gap between cells. These technologies greatly improve the module efficiency, with solar cells from the production lines of 210 mm high efficiency PERC cells.
Earlier this year, Trina Solar was the first to release a new generation of 670W Vertex
module, using 66 pieces of 210 mm p-type PERC cells. This time, Trina solar demonstrates that its technology leadership in 210 commercialized modules, not
only in terms of ultra-high power, but also the ultra-high efficiency.
“We are very pleased to announce the latest achievement of our R&D team at the
State Key Laboratory of Photovoltaic Science and Technology. To the best of our
knowledge, it is the first large-area p-type commercial module with aperture
efficiency over 23%,” say Dr Yifeng Chen, Trina Solar head of high efficiency cell and
module R&D center. “Improving module efficiency is key to helping customers to save land, labor and cables, etc. Trina Solar always focuses on developing leading-edge PV technologies and products to achieve commercial success of customers with our innovations.”
