JA Solar multi-si solar cells reach record efficiency levels

SHANGHAI, CHINA: JA Solar Holdings Co. Ltd, one of the world's largest manufacturers of high-performance solar power products, announced that its multi-crystalline silicon ("multi-Si") solar cells have reached an industry-leading conversion efficiency of 18.3 percent.

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 mm2) 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 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."
