Trinasolar has once again raised the bar in solar technology, achieving a record-breaking 25.9 per cent efficiency with its 210 ×182 mm² n-type bifacial TOPCon cell.
This milestone, verified by Germany’s Institute for Solar Energy Research (ISFH CalTeC), marks Trinasolar’s 27th world record in solar cell and module efficiency or output power, underscoring its leadership and innovation within the photovoltaic (PV) industry.
The breakthrough was made possible by Trinasolar’s signature rectangular wafer design, a 210 ×182 mm² n-type phosphorus-doped Cz silicon wafer known for its high minority carrier lifetime.
Enhanced by cutting-edge tunnel oxide passivation, advanced boron-doped emitters, light-trapping techniques, and fine line printing, this industrial-size bifacial cell reaches an efficiency milestone unmatched in large-area TOPCon technology.
“We are delighted to announce the wonderful achievement by our research team. It not only sets a new record for large-area TOPCon cells but also breaks the world record for n-type TOPCon cells created and maintained by Fraunhofer ISE since 2017,” Dr. Chen Yifeng, Vice President at Trinasolar said.
“TOPCon is the dominating technology in [the] PV industry, with its high level of industrialisation, higher customer value, and lower cost. Our accomplishment indicates the great potential of TOPCon technology in the future.”
Since pioneering n-type technology research in 2015, Trinasolar has committed to evolving TOPCon innovation and remains a leader in the field with over 500 patents by mid-2024.
