Trina Solar Limited (Changzhou, China) on October 18th, 2016 announced that its State Key Laboratory of PV Science and Technology of China (SKL PVST) has set a new world record of 19.86% aperture efficiency for its high-efficiency “Honey Plus” multi-crystalline silicon (mc-Si) solar module, which contains 120 pieces of P-type mc-Si solar cells (156x78 mm2).

The result has been independently verified by the Fraunhofer ISE CalLab in Germany.

The record-breaking solar PV module, using the Company's independently developed high performance mc-Si wafers with a high minority carrier lifetime, is manufactured with a number of advanced in-house technologies including half-cell interconnection, passivated emitter and rear cell (PERC) technology and highly efficient light trapping.

Following the previous efficiency record of 19.14% on a 1.515 m2 aperture-area announced in April 2015, the SKL PVST successfully achieved a new aperture-area efficiency record of 19.86% on a module area of 1.514 m2 within one year and a half.

The new record represents an increase of more than 0.7 percentage points, or approximately 3.8% higher.

“We are very delighted to announce the latest achievement from our research team at the SKL PVST,” said Dr. Pierre Verlinden, Vice-President and Chief Scientist of Trina Solar.

“The efficiency of PV modules is one of the key parameters to estimate the final Levelised Cost of solar Electricity (LCOE). This 19.86% aperture efficiency result that Trina Solar achieved demonstrates the huge potential for future multi-crystalline p-type silicon research. It is also a leap forward in the trend of continuous efficiency improvements of crystalline silicon solar modules.”
