Trina Solar Ltd. says its State Key Laboratory of PV Science and Technology of China has set a new record for industrial high-efficiency p-type monocrystalline silicon (c-Si) solar cells.

The record-breaking p-type mono-crystalline silicon solar cell was fabricated on a large-size industrial boron-doped Cz-Si substrate with an advanced Honey Plus process that integrated both front and back surface passivation. The 156 x 156 mm2 solar cell reached a total-area efficiency of 22.13%. This result has been independently confirmed by the Fraunhofer ISE CalLab in Germany.

This efficiency record breaks the previous record of 21.4% for the same type of solar cell that was also established by the State Key Laboratory of Trina Solar in 2014, demonstrating an efficiency improvement of 0.73 percentage points within only one year.

‘We believe that this is the highest efficiency ever reported to date for a p-type industrial solar cell,’ says Dr. Pierre Verlinden, vice president and chief scientist of Trina Solar. ‘This Honey Plus solar cell, fabricated with a low-cost industrial processâ�¦is just 2.87 percent below the world record of 25 percent established by the University of New South Wales with a 2 x 2 cm2 laboratory solar cell.’
