Trina Solar’s State Key Laboratory of PV Science and Technology has set a new world record for high efficiency p-type multi-crystalline silicon PV modules.
The Chinese company said its Honey Plus multi-crystalline silicon module had reached a new module efficiency record of 19.14% with an aperture area of 1.515 m2 — a value that was independently confirmed by the National Center of Supervision and Inspection on Solar Photovoltaic Product Quality (CPVT) in Wuxi, China.
The result is a new world record for a multi-crystalline silicon module composed of 60 high-efficiency Honey Plus multi-crystalline silicon cells (156×156 mm2), fabricated with advanced technologies that include back surface passivation, local back surface field and half-cell module technologies developed by Trina Solar.
The multi-crystalline Honey Plus solar cells, the brand name for Trina’s PERC solar cells, are now in mass production. The half-cell module technology is not currently part of the Honey Plus products, but will be incorporated at a later date.
"To the best of our knowledge, this is the first time that a multi-crystalline Silicon PV module reaches an efficiency higher than 19%," said Pierre Verlinden, Trina vice president and chief scientist. "It demonstrates that multi-crystalline silicon PV modules can reach an efficiency level that was reserved to the most efficient solar cells before, such as mono-crystalline IBC or heterojunction cells."
Verlinden added that the achievement was the result of a very close collaboration among Trina’s silicon crystallization, solar cell and module scientists. "We believe that innovation is playing the very essential role in Trina’s sustainable growth and long-term success."
