JA Solar Starts Mass Production of PERCIUM Solar Cell, Conversion Efficiency Reaches 20.4%

SHANGHAI, June 23, 2014 /PRNewswire/ -- JA Solar Holdings Co., Ltd. (Nasdaq: JASO) ("JA Solar" or the "Company"), one of the world's largest manufacturers of high-performance solar power products, launched mass production of its PERCIUM solar cell on June 20th. The PERCIUM solar cell, the first P-TYPE solar cell in industry that surpasses a conversion efficiency of 20%, has reached an average conversion efficiency of 20.4%. The 6x10 PERCIUM cells module, which has reached an average power rating of 285W, is expected to be put into mass production one week later. The preparation for mass production has taken only three months since the new product release early this year and the module is expected to reach an average power rating of 290W by the end of the year.

High conversion efficiency and high reliability are two aspects the solar industry highly values as the next step of development. It's also what makes JA Solar products so outstanding. Early this year, JA Solar launched the 6x10 PERCIUM cells module in Japanese, British, Israeli, Chinese and German markets and has received positive responses, especially from European and Japanese markets. Since then JA Solar has received plenty of enquiries and order forms.

To meet the increasing demands of customers, JA Solar has completed preparations for mass production within a short time and will continue to expand the capacity of PERCIUM solar cells. Currently, the company has one PERCIUM solar cell production line and will have four this October. It expects to have eight in 2015. The capacity of PERCIUM solar cells is expected to reach 170MW by the end of this year and 350MW 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."
