JA Solar announces efficiency of over 19% for its multicrystalline solar cells

Chinese solar company JA Solar Holdings Co. Ltd. announced it has achieved a conversion efficiency of over 19% for its multicrystalline silicon (multi-Si) solar cell. The company has not said if the results were certified by an independent entity. JA Solar plans to integrate the new multicrystalline technology into its commercial manufacturing lines in the second half of 2014.
In August, JA Solar achieved a first record conversion efficiency of 18.3% for an industrial size (156x156 mm2) multicrystalline silicon solar cell. The result was certified by the Yangzhou Opto-Electrical Products Testing Institute. At the time, JA Solar said it planned to integrate the new technology into its commercial manufacturing lines within the following 6 months.
