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.

JA Solar, a world-leading manufacturer of high-performance photovoltaic 
products, 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.

Mr. Jin Baofang, JA Solar's Chairman of the Board of Directors and CEO, stated, 
"JA Solar is committed to building respect for and recognizing the importance 
of intellectual property. While focusing on research and innovation, we apply 
advanced third-party technologies to further optimize 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 realization of grid parity."
