China-based PV module manufacturer Trina Solar Ltd. says that its lab has set a new world record of 19.86% aperture efficiency with the company’s “Honey Plus” multicrystalline silicon (mc-Si) solar module, which contains 120 pieces of P-type mc-Si solar cells (156 x 78 mm2). According to the company, the Fraunhofer ISE CalLab in Germany has independently verified the result.
Trina Solar says the record-breaking solar module is manufactured with a number of advanced in-house technologies, including half-cell interconnection, passivated emitter and rear cell (PERC) technology and efficient light trapping. Following the previous efficiency record of 19.14% on a 1.515 m2 aperture area, the company’s State Key Laboratory of PV Science and Technology of China successfully achieved a new aperture-area efficiency record of 19.86% on a module area of 1.514 m2 within a year-and-a-half, according to Trina Solar. The new record represents an increase of more than 0.7 percentage points, or approximately 3.8% higher.
“The efficiency of PV modules is one of the key parameters to estimate the final levelised cost of solar electricity. This 19.86 percent aperture efficiency result that Trina Solar achieved demonstrates the huge potential for future multicrystalline p-type silicon research. It is also a leap forward in the trend of continuous efficiency improvements of crystalline-silicon solar modules,” said Dr. Pierre Verlinden, vice president and chief scientist of Trina Solar.
