Multi-crystalline silicon solar cell claims 21.25 percent efficiency record
The record-breaking p-type multi-crystalline silicon solar cell was fabricated on a high-quality mc-Si substrate with a process that integrates advanced Honey Plus
technologies including back surface passivation and local back surface field. Trina’s 156 x 156 mm solar cell reached a total-area efficiency of 21.25%.
The result has been independently confirmed by the Fraunhofer ISE CalLab in Germany. The efficiency record breaks the previous 20.76% efficiency world record for mc-Si solar cells also established by Trina Solar one year ago. To set the new record, only low-cost industrial processes which can be easily integrated into large-volume production were used.
"We are very pleased to announce the new efficiency results achieved by our scientists and researchers at the State Key Laboratory of PV Science and Technology. To the
best of our knowledge, this is the first time ever that a multi-crystalline silicon solar cell has been able to achieve a conversion efficiency of over 21%," said Dr. Pierre Verlinden, Vice-President and Chief Scientist of Trina Solar. "This exciting result shows that the development path toward higher efficiencies continues to be bright, even for silicon."
