Trina Solar Limited announced that its State Key Laboratory of PV Science and Technology of China (SKL PVST) has set a new world record of 19.86 percent aperture efficiency for its high-efficiency “Honey Plus” multicrystalline silicon (mc-Si) solar module, which contains 120 pieces of P-type mc-Si solar cells (156 x 78 mm2). The result has been independently verified by the Fraunhofer ISE CalLab in Germany.
Inside the module
The record-breaking solar 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 percent 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 percent 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.
