The fifth advanced component technology and packaging materials forum 2021 will be held in Changzhou on August 5. Experts from Jingke, Atlas, Zhonglai, Huansheng photovoltaic, Trina Solar, GCL, Swick, Jingao, Chint, amaton, Dongfang Risheng, Mavericks and PV InfoLink will make important speeches.
On July 2, 2021, after being tested by the Institute f ü R solarenegieforschung in Hameln (ISFH), a world recognized authoritative testing institution, Anhui Huasheng joined hands with Maiwei Co., Ltd. the conversion efficiency of M6 hjt battery in their heterojunction R & D project reached a record 25.26%, surpassing the record of 25.23% of M6 heterojunction battery certified by ISFH in June!
25.26%, this efficiency not only equaled the current world record of full-size heterojunction battery, but also it is worth noting that this is the second in the world to increase the current density of hjt battery to 40mA / cm except Kaneka in Japan since 2015 ² Manufacturer. At the same time, the open circuit voltage of the champion battery is still maintained above 745mv, which has a high reference value for the technical route of improving the efficiency of heterojunction battery.
Dr. Wang Wenjing, CTO of Huasheng, said: "at present, Huasheng has successfully tied the world record of heterojunction battery efficiency, but under the same efficiency, Huasheng's battery chip area is larger, which is one of the mainstream battery sizes in the current market and has guiding significance for large-scale mass production. At present, the current of the champion chip is second only to Kaneka in Japan. The most difficult thing for heterojunction batteries is that it is difficult to improve the current. This time, while the current is increased, the on voltage is still high, which looks for a new way to improve the efficiency of hjt batteries in the future. "
