JA Solar Holdings Co. Ltd has developed a multi-crystalline silicon (multi-Si) solar cell that claims to reach conversion efficiency up to 20 per cent. The research team from the company revealed that through the use of its advanced proprietary light trapping and surface passivation technologies, they were able to achieve one per cent increase in conversion efficiency only nine months after hitting the 19 per cent efficiency in its multi-Si cells.

"JA Solar set a new world record for multi-Si cell efficiency by breaking the 20 per cent barrier. This accomplishment once again demonstrates JA Solar's unrivalled ability to advance PV technology, and creates value for our customers by increasing power generation and reducing installation costs," stated Yong Liu, COO of JA Solar.

"Consecutive record-breaking results by our multi-Si solar cells are a great achievement for our R&D team. But, we have only just begun. The confidence we had in surpassing 20 per cent efficiency this year extends now to our expectation to realise even more efficiency gains in the quarters ahead. Furthermore, with these new high performance cells as a foundation, we anticipate setting new performance records at the module level in the near future," noted Wei Shan, chief scientist and general R&D manager at JA Solar.

JA Solar plans to mass produce multi-Si cells using its latest technology and integrate its recently developed high-efficiency multi-Si cells into commercial module assemblies in 2015.
