JA Solar Becomes 1st Firm to Mass-Produce Mono PERC Modules With Ga-Doped Wafers

JA Solar has become the first firm in the world to mass-produce high-efficiency Mono PERC MBB cells and modules using Ga-doped wafers.

With the recent introduction of Ga doped wafers company wide, JA Solar becomes the first firm in the world to mass-produce high-efficiency Mono PERC MBB cells and modules using Ga-doped wafers. The world-leading manufacturer of high-performance photovoltaic products has announced that all its production lines of Mono PERC MBB Cells and related modules can be switched to produce modules and cells adopting Ga-doped silicon wafers. Integrating with PERC-SE technology and large-size wafers, Ga doping technology consistently improves the performance of both cells and modules. 

In 2019, Shin-Etsu Chemical granted its “Ga-doped silicon wafers for making solar cells” IP rights to JA Solar, which paved way for JA Solar to use Ga doped wafers worldwide. The application of Ga-doped silicon wafers to solar cells can effectively mitigate the initial light-induced degradation (LID) issue, which limits the performance of solar modules with traditional Si wafers. 

The Ga-doped silicon wafer technology allows for improved performance in power generation, particularly the much better stability, ensuring customers with long-term benefits.

Jin Baofang, JA Solar’s Chairman of the Board of Directors and CEO, stated, “JA Solar is committed to building respect for and recognising the importance of the intellectual property. While focusing on research and innovation, we apply advanced third-party technologies to further optimise our product performance. The application of Ga-doped wafers in the manufacturing of mono PERC MBB cells and modules enables us to provide our global customers with better solar products and help the realisation of grid parity.”

In January, the firm had revealed that it is planning to invest CNY 6.6 billion (USD 947.7 million) for the establishment of two new solar PV manufacturing plants in China with a combined annual production capacity close to 15 GW. The company had signed a framework agreement with the management committee of a local industrial zone in China’s Zhejiang province regarding the proposed investment, it said in a bourse filing. The firm intends to build a production facility in Yiwu city where it will be able to make 5 GW of solar PV cells per year, while a new 10-GW factory will produce PV modules.
