JA Solar Commences Mass Production of Metal Wrap-through Solar Cells

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."
