30.6%, 829W! Double world record breaking

Trina Solar announced today that its large-area perovskite/crystalline silicon tandem modules independently developed by the National Key Laboratory of Photovoltaic Science and Technology have made a major breakthrough in conversion efficiency. After independent testing and certification by the Fraunhofer Institute for Solar Energy Research (Fraunhofer ISE) in Germany, the efficiency of the laboratory tandem modules with an area of ​​1185cm² reached 30.6%, making it the world's first photovoltaic company to achieve a tandem module efficiency exceeding the 30% mark.

This achievement has been officially included in the global solar cell world record "Solar cell efficiency tables" (Version 66) edited by Professor Martin Green. This globally recognized authoritative solar cell record table demonstrates the high recognition of Trina Solar's technological achievements by the international authoritative academic community. At the same time, the large-area perovskite/crystalline silicon two-terminal tandem cell module independently developed by the laboratory has a module area of ​​3.1m². After being certified by the TÜV SÜD test laboratory, the module peak power reached 829W, once again refreshing the power of large-size photovoltaic module products. This is another major breakthrough for Trina Solar in the field of stacked technology after the first breakthrough of 808W in March this year, further consolidating the company's leading position in the field of cutting-edge photovoltaic technology.

The stacked modules released this time are all based on 210mm large-size stacked cell technology. On this basis, the technical team focuses on the intrinsic characteristics of perovskite materials and develops flexible low-shading photoconductivity technology, material adaptive heterogeneous connection technology and multi-scale full-spectrum photon management technology, optoelectronic optimization and synergistic drive to give full play to the efficiency advantages of stacked cells. This achievement is another major technological breakthrough after the large-area full-size module power exceeded 808W, marking that Trina Solar has achieved technological breakthroughs in the field of perovskite/crystalline silicon stacked technology from cell efficiency to module efficiency to full-size module power in multiple dimensions and levels.

"Perovskite/crystalline silicon stacking technology is one of the core directions of the next generation of high-efficiency photovoltaics. This time, we took the lead in achieving a double breakthrough of 30% efficiency of laboratory stacking modules and 829W power of full-size large-area stacking modules, which means that this technology has gradually moved from a 'laboratory miracle' to an 'engineering reality'." Gao Jifan, Chairman and CEO of Trina Solar and Director of the National Key Laboratory of Photovoltaic Science and Technology, said that this achievement is not only a technological breakthrough, but also represents the key node of perovskite/crystalline silicon stacking technology moving from the concept verification stage to large-scale application. Trina Solar's continued investment in this field is expected to promote the overall efficiency level of the photovoltaic industry into a "new era of 30%+ perovskite/crystalline silicon stacking battery modules."
