Pilot production of the cells began in May with commercial volume production planned in the second half of this year.
The companies 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 in the U.S. and at JA Solar’s research and development center in China.
JA Solar recently reported it has achieved conversion efficiency of 18.9 percent for its Secium solar cells: these results have been independently certified by The Fraunhofer Institute for Solar Energy Systems (ISE) in Germany.
The new cost effective, high efficiency 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, said the company.
