SHANGHAI, China, April 23, 2013 (GLOBE NEWSWIRE) -- JA Solar Holdings Co., Ltd. (Nasdaq:JASO) ("JA Solar" or the "Company"), one of the world's largest manufacturers of high-performance solar power products, today announced it has commenced mass production of metal wrap-through ("MWT") solar cells. The Company's MWT monocrystalline and multicrystalline cells have an average conversion efficiency of 19.6% and 18.1%, respectively, and a peak conversion efficiency of 20.0% and 18.6%, respectively. By moving the emitter contact from the front to the rear of the cell via laser-drilling and plug paste printing, MWT technology reduces the metallized area on the front side, increasing overall conversion efficiency. When assembled into modules, MWT cells require no welding and are therefore subject to lower power loss and a lower cell-breakage rate. "MWT is at the core of the next generation of module technology, and represents a significant breakthrough in terms of power output and conversion efficiency," said Mr. Yong Liu, CTO of JA Solar. "Mass production of MWT cells marks a significant milestone in JA Solar's ongoing technological leadership in the global solar industry."
