JA Solar's 18% Conversion Efficiency High-Efficiency Polycrystalline Battery "Crystal" Enters Large-Scale Production

With the opportunity of the German Intersolar, Jinao announced that its highly efficient polycrystalline battery “Maple” has been officially launched in mass production. The average conversion efficiency after mass production can reach 17.5% and the maximum can reach 18.2%. This is a milestone event in the field of polycrystalline silicon solar cells.

Jingfeng Battery was successfully developed by JA Solar in March 2011. This product has applied the “Super Large Grain Quasi-Single Crystal Ingot” technology independently researched and developed by Jingao. Its remarkable features are low cost and high efficiency. Compared with the process cost, polysilicon ingots have a rather significant process cost advantage compared to Czochralski single crystals; in terms of quality, Czochralski single crystal conversion rate can reach 18%, and polysilicon is generally about 16-17%; The highest conversion rate of quasi-monocrystalline silicon “Maple” products produced using the new ingot technology can be comparable to that of monocrystalline silicon, which is as high as 18.2%; and the cost is comparable to that of polycrystalline silicon ingot casting.

"This technology uses polysilicon ingot technology to obtain single-crystal quality products, making up for the low conversion efficiency of polycrystalline cells and the small yield of single-crystal cells. The breakthrough in this technology has led to a substantial drop in the cost of polycrystalline silicon ingots; With the general reduction of European subsidy policies, only by continuously reducing the production cost of crystalline silicon can we promote the realization of the universal PV power generation. JA Solar insists that the research and development of new technologies is the core element for the development of the photovoltaic industry!” Shigeo CEO Fang Peng Evaluation said.

Crystalline high-efficiency polycrystalline battery can be used to achieve a power of 250W for 60-cell modules and 300W for 72-cell modules. The conversion efficiency of the module can reach over 15%, which has reached or even surpassed that of ordinary single crystals. The power of the components also significantly reduces the cost of the components. The solar photovoltaic module products using Jingfeng High-efficiency Polycrystalline Battery are 10% more than ordinary modules, which is very suitable for roof projects.

The solar photovoltaic module products using Jingfeng high-efficiency polycrystalline cells are 10% more than the normal components, which reduces the system cost and installation cost per watt. This system not only has a low weight, but also releases more power in a limited area. These characteristics make it very suitable for roof projects.

"We are very pleased to use the Intersolar platform to present our new products and new technologies to the world. We are also very much looking forward to letting more customers feel the value of Jinao!"
