JA Solar Holdings Co. Ltd. has signed strategic agreements with Innovalight Inc. JA Solar and Innovalight also announced that they have signed a strategic agreement to co-develop solar cells with conversion efficiencies exceeding 20 percent.

Development will be performed at both Innovalight's headquarters in California and at JA Solar's R&D center in China.

"We are very excited about the strong partnership we have established with Innovalight," said Dr. Peng Fang, chief executive officer at JA Solar. "JA Solar will continue to stay at the forefront of solar cell technology and commercial production of high-efficiency solar cells through partnerships between our internal R&D group and external partners like Innovalight."

JA Solar has achieved conversion efficiency of 18.9 percent for its SECIUM solar cells and these results have been independently certified by The Fraunhofer Institute for Solar Energy Systems (ISE) in Germany. The new solar cells enable substantially better spectral response at short wavelengths in comparison with standard solar cells and therefore have higher conversion efficiency than conventional solar cells from other manufacturers, the company said.
