Trina Solar's State Key Laboratory of Photovoltaic Science and Technology (SKL) announced that its proprietary Vertex high-efficiency p-type monocrystalline silicon module, based on 66 pcs 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 is 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-Musbar (MBB) technology to improve optical shading, and developed a new hybrid soldering technology to minimize the gap between cells. These advantages greatly improve the module efficiency, with solar cells from the production lines of 210 mm high efficiency PERC cells.
