Trina Solar's State Key Laboratory of PV Science and Technology (SKL PVST) 
announced its proprietary industrial larger-area 210mmx210mm high-efficiency 
PERC solar cell in mass production, has achieved the efficiency of 23.56%, 
setting a new record for 210 P-type monocrystalline silicon PERC cells. This is 
independently confirmed by the third party National Center of Supervision and 
Inspection on Solar Photovoltaic Product Quality (CPVT).

The advanced 210 PERC cells were fabricated in the mass production lines by the 
R&D group with delicate device and process optimization, using industrial 
feasible manufacturing equipments and materials.

Dr. Yifeng Chen, head of high efficiency cell and module R&D center in Trina 
Solar, said, "We are proud to announce the latest achievements developed by our 
technical team, to realize the batch efficiency over 23.5% for larger-area 
210mm high-efficiency PERC cells in production. This demonstrated that 210 
cells can achieve very high efficiency in reality. Our technical team will 
continue to focus on transfer innovative technologies to manufacturing to 
consolidate our technology leadership in high efficiency cells mass production."

At the end of June 2021, the SKL announced that its Vertex high-efficiency 
p-type monocrystalline silicon module has achieved a record aperture module 
efficiency of 23.03%, based on 66 pcs of 210 mm x 210 mm high-efficiency PERC 
cells, which is independently confirmed by both TUV Rheinland and TUV Nord with 
identical efficiency result.
