JA Solar Multi-Si Solar Cells Reach Record Efficiency Levels

SHANGHAI, China, Aug. 1, 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 that
its multi-crystalline silicon ("multi-Si") solar cells have reached an
industry-leading conversion efficiency of 18.3%.

The new level of conversion efficiency, which has been independently certified
by the Yangzhou Opto-Electrical Products Testing Institute, eclipses that of
all previously certified industrial size (156x156 mm^2) multi-Si solar cells.
The breakthrough follows JA Solar's recent progress in high-crystal quality,
low dislocation density multi-Si casting and wafering. JA Solar's R&D and
production teams plan to integrate the new technology into existing
manufacturing lines for assembly into modules for commercial use.

"This latest advance is a real testament to the exceptional R&D work going on
at JA Solar, and another key step in our efforts to meet the growing demand
for high-performance solar power products," said Mr. Yong Liu, CTO of JA
Solar. "The superior conversion efficiency we've achieved with our multi-Si
cells and the rest of our product offering creates significant value for
customers as it increases power generated per square foot and lowers
installation cost per watt."

"These record-breaking results are a testament to the continued leadership of
our R&D team," added by Dr. Wei Shan, chief scientist and general R&D manager
of JA Solar. "We look forward to leveraging our improved multi-Si technology
to meet the needs of our customers and project partners."
