Aug. 19, 2013 - JA Solar today announced that its p-type mono-crystalline silicon solar cells, dubbed "PERCIUM," have surpassed 20% conversion efficiency.
The newly achieved conversion efficiency, which has been independently confirmed and certified by the Fraunhofer ISE's photovoltaic calibration laboratory (CalLab) in Freiburg, Germany, sets a new level for industrial size (156x156 mm2) solar cells using p-type mono-Si wafers.
The breakthrough follows JA Solar's recent announcement of the new efficiency of its multi-crystalline silicon solar cells. JA Solar plans to introduce the new cell technology into mass production within the next six months and integrate the new cells into module assembly lines for commercial use.
"This latest above 20% conversion efficiency of solar cells using p-type mono-Si wafers is of great importance in terms of cost-effectively manufacturing high-performance solar cells and modules," said Mr. Yong Liu, CTO of JA Solar. "It is also a further boost to our efforts to meet the growing demand for high-performance solar power products."
"This result builds on the momentum that our R&D team has generated in recent months," added Dr. Wei Shan, chief scientist and general R&D manager of JA Solar. "We have repeatedly achieved average conversion efficiency of over 20% since May of this year on over 10,000 cells. We're fully confident in bringing such products to serve our clients' needs. Our R&D team has an excellent track record of commercializing cutting-edge technologies and we look forward to transitioning these high-efficiency cells into mass production soon."
