BEIJING, March 19, 2020 /PRNewswire=KYODO JBN/ --

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."
