Shanghai, China, February 2014 - JA Solar Holdings Co Ltd, one of the world's largest manufacturers of high-performance solar power products, has announced that its multi-crystalline silicon ("multi-Si") solar cells have surpassed 19% conversion efficiency.

This latest improvement in efficiency, achieved using advanced cell technology recently developed by JA Solar's R&D team, follows the Company's announcement in August 2013 that its multi-Si cells had achieved 18.3% conversion efficiency, an industry record at the time.

"The new cells are a further testament to JA Solar's unrivaled efforts to push the boundaries of PV technology, and their superior power generation per unit of area and lower installation cost per watt will deliver significant value to customers."

JA Solar plans to commence mass production of its new multi-Si cells and integrate them into module assembly lines for commercial use in the second half of 2014.
