JA Solar (JASO) cemented its partnership with Innovalight of California today, signing a 3 year supply agreement for silicon nanoparticle ink which is a key component in JA Solar’s new SECIUM high efficiency solar cells which are expected to move into volume production very soon.  JASO has been able to achieve efficiency rates of 18.9% and the two companies are working together to push that to over 20%.

“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,” he added.

JASO shares are giving some back today, down 6%, but were up nearly 40% in just the past two weeks and looking increasingly bullish.  There is now significant support around the $5 level with  the next level of resistance around the 2010 highs.  Technically, it remains one of the strongest solar stocks.
