Trina Solar’s PV cell technology hit another efficiency record. Its Honey Plus p-type mono-crystalline silicon PV cells reached a record-high conversion efficiency of 22.13% at its State Key Laboratory of PV Science and Technology of China. The record-breaking cell was manufactured through PERC technology.
"We believe that this is the highest efficiency ever reported to date for a p-type industrial solar cell," said Dr. Pierre Verlinden, Vice-President and Chief Scientist of Trina Solar. “Our goal is to continue pushing technological innovations and implementing laboratory breakthroughs into commercial production. We will continue to develop high efficiency solar cell products to further reduce the cost of photovoltaic power generation.”
Trina Solar has achieved several PV cell efficiency records in the recent. With PERC technology, its R&D teams reached an efficiency of 21.25% with multi-crystalline silicon cells and the 22.13% record with mono c-Si cells. Both records were achieved by p-type cells so that Trina Solar expressed an enormous potential of such technology.
The record-breaking p-type mono c-Si 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 efficiency of 22.13% has been independently confirmed by the Fraunhofer ISE CalLab in Germany.
In 2014, Trina Solar used the same technology and reached a 21.40% efficiency at the same laboratory. With the self-broken record, Trina Solar successfully improve 0.73% of conversion efficiency for the type of PV cell within only one year.
