JA Solar Holdings Co., Ltd. (Nasdaq: JASO), one of the world’s largest manufacturers of high-performance solar power products, today announced that it achieved 20% solar energy conversion efficiency in its multi-crystalline silicon solar cell. By using advanced proprietary light trapping and surface passivation technologies, the JA Solar research team attained this absolute 1% increase in conversion efficiency only nine months after announcing the realization of 19% efficiency in its multi-Si cells.
Added Dr. Wei Shan, Chief Scientist and General R&D Manager: “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% efficiency this year extends now to our expectation to realize 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.”
JA Solar intends to mass produce multi-Si cells using its new technology and integrate its new high-efficiency multi-Si cells into commercial module assemblies in 2015.
