JA Solar’s IP on Bifacial PERC Technology Patented in Japan
JA Solar Holdings Co., Ltd., a world-leading manufacturer of high-performance photovoltaic products, announced that its patent application for protecting the company’s intellectual property of bifacial PERC cell and module technology has been granted by the Japanese Patent Office.
JA Solar has been a company fully committed to the innovation and advancement of photovoltaic technology since its inception by devoting enormous resources on its R&D efforts, and has maintained its technological leading position in the photovoltaic industry globally. JA Solar filed an invention disclosure of “A Bifacial Light-Absorbing Solar Cell with Localized AI-BSF and the Method of Making It” to National Bureau of Intellectual Properties of China in early 2013, and the patent was subsequently granted in March 2016. The bifacial PERC technology utilizes the backside of a PERC cell to receive scattered and reflected lights from the ground, resulting in higher energy generation on module level. The patent puts JA Solar in a unique position to hold the core intellectual property rights associated with bifacial PERC cells and modules. The latest approval of this patent application by the Japanese Patent Office is a manifestation of JA Solar's technological innovativeness, as well as the legal recognition and protection for the IP rights in Japan.
JA Solar has started mass production of double-glass bifacial PERC modules since the first quarter of 2017. The bifaciality of such modules capable of absorbing lights from both sides, combined with its high resistance to wear-tear, abrasion and corrosion, and close to zero water permeability, this high-end, high-quality double glass bifacial PERC modules are especially suitable for coastal areas and climatically challenging environments, providing long-term stability of solar energy generation particularly for utility-scale PV systems. Bifacial PERC technology is currently regarded as one of the most advanced and cost-effective technical solutions to reduce the levelized cost of energy (LCOE) of solar energy generation.
Dr. Wei Shan, Chief Technology Officer of JA Solar, commented, "JA Solar has always been focusing on the research and development, as well as and the cost-effective production of high-efficiency PV products. Our industry-leading cell and module technology assures our products’ quality and performance, resulting in our shipments to the Japan market well ahead of our peers as JA Solar was the top module supplier in Japan in the first half of 2018. We believe that our bifacial PERC technology patented in Japan will further strengthen JA’s position and expand our market share in the region to better service our customers with high-quality products.”
