Trina Solar Breaks 27th Efficiency Record
Trina Solar, a leading Chinese solar manufacturer, has once again showcased its commitment to innovation by achieving a new world record for solar cell/module conversion efficiency. The company’s n-type bifacial i-TOPCon cell reached an impressive efficiency of 25.9 per cent, marking Trina Solar’s 27th world record in this field.
Renowned for its pioneering work in the solar industry, Trina Solar continues to push the boundaries of technology and research. The recent milestone, certified by the Institute for Solar Energy Research in Hamelin (ISFH CalTeC) in Germany, highlights the company’s dedication to advancing solar innovation.
Breaking New Ground in Solar Technology
The record-breaking achievement was made possible by Trina Solar’s industrial larger-area 210 ×182 mm² n-type bifacial i-TOPCon cell. This breakthrough not only sets a new benchmark for large-area industrial TOPCon solar cells but also demonstrates the company’s expertise in this field.
Trina Solar embarked on its TOPCon solar technology research and development journey in 2015, amassing over 500 patents in the process. The latest record utilised the company’s innovative rectangle wafer design, featuring the optimal dimensions of 210 ×182 mm², coupled with an n-type phosphorus-doped Cz silicon wafer substrate for enhanced performance.
Technological Advancements
The record-setting solar cell incorporated cutting-edge technologies such as tunnel oxide passivating contact, advanced boron-doped emitter, advanced light trapping, and very fine line printing. These innovations culminated in a remarkable front side efficiency of 25.9% for the industrial size bifacial n–type i-TOPCon cell.
Dr. Chen Yifeng, vice president at Trina Solar, expressed delight at the achievement, emphasising the significance of TOPCon technology in the PV industry. This breakthrough not only surpasses previous records but also underscores the potential of TOPCon technology for future applications.
“We are thrilled to announce this remarkable accomplishment by our research team. It not only establishes a new benchmark for large-area TOPCon cells but also surpasses the world record for n-type TOPCon cells, previously held by Fraunhofer ISE since 2017,” stated Dr. Chen Yifeng.
“TOPCon technology is a game-changer in the PV industry, offering high industrialisation levels, increased customer value, and reduced costs. Our success underscores the immense potential of TOPCon technology in shaping the future of solar energy.”
