JA Solar Announces Mass Production of 20.4% Efficient Solar Cell


JA Solar announces the mass production of its PERCIUIM solar cell. The P-TYPE solar cell reaches 20.4% average conversion efficiency, and JA Solar plans to boost production to over eight times their current capacity.


JA Solar Holdings Co., Ltd. (Nasdaq: JASO), one of the world’s largest manufacturers of high-performance solar power products, began mass production of its PERCIUM solar cell on June 20. The PERCIUM solar cell, the first P-TYPE solar cell in the industry that surpasses a conversion efficiency of 20%, has reached an average conversion efficiency of 20.4%. The 6×10 PERCIUM cells module has reached an average power rating of 285 W and is expected to reach 290 W by the end of the year. The preparation for mass production has taken only three months since the new product release earlier this year.


High conversion efficiency and high reliability are two key aspects the solar industry highly values to bring costs down and speed up development. Early this year, JA Solar launched the 6×10 PERCIUM cells module in Japanese, British, Israeli, Chinese, and German markets, where it has received positive responses, especially in Europe and Japan.


To meet the increasing demands for high-efficiency modules, JA Solar has completed preparations for mass production within a short time and will continue to expand the capacity of PERCIUM solar cells. JA Solar currently has one PERCIUM solar cell production line and will increase this to four by October. It expects to have eight production lines running in 2015. The capacity of PERCIUM solar cells is expected to reach 170 MW by the end of this year and 350 MW next year.


“High conversion efficiency can bring about low system cost per Watt, which means low BOS, transportation, installation and land cost,” said Mr. Yong Liu, chief operation officer of JA Solar. “The PERCIUM solar cell uses Passivated backside and local BSF technology to ensure excellent low-light performance of PERCIUM cells module. High cost performance on the system side can help to reduce the cost of power per KWH.”


JA Solar is not the first company to reach 20% efficiency with its solar cells. First Solar recently announced 20.4% efficiency with its cadmium-telluride (CdTe) PV solar cells, which is a world record for this cell type. JA Solar is unique though in that it is putting its high-efficiency cells into mass production in the very near future, which is good news for buyers looking to reduce costs.
