JA Solar Holdings recently announced that its p-type mono-crystalline silicon ("mono-Si") solar cells, a new family of high-performance solar cells dubbed "PERCIUM," have surpassed 20 per cent conversion efficiency.

"This latest above 20 per cent 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 Yong Liu, JA Solar's CTO. "It is also a further boost to our efforts to meet the growing demand for high-performance solar power products."

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 an industry-leading level for industrial size (156x156mm2) solar cells using p-type mono-Si wafers.

The breakthrough follows JA Solar's recent announcement of the industry-leading efficiency of its multi-crystalline silicon ("multi-Si") solar cells. JA Solar plans to introduce the new cell technology into mass production within the next six months and integrate the new high-efficiency cells into module assembly lines for commercial use.

"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 per cent 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."
