Thanks to CTOnews.com netizens, assassins for their clues delivery! CTOnews.com October 17 news, according to Jingke Energy official account news, recently Jingke Energy announced that its research institute independently developed 182N high efficiency monocrystalline silicon battery technology has made a major breakthrough, by the authoritative third-party testing and certification body the testing laboratory of the Chinese Academy of Metrology, the overall accumulator battery conversion efficiency reached 26.1%. Once again, a new world record for conversion efficiency of large area N-type single crystal passivation contact (TOPCon) batteries with sizes of 182 and above has been created.

According to Jingke Energy, through unremitting efforts to tackle key technical problems, the R & D team took the lead in developing a number of advanced technologies suitable for large sizes, such as interface defect repair, high transmission polysilicon film and ultra-fine metal electrodes based on laser SE, as well as self-developed complete sets of HOT high efficiency battery technology and material optimization, achieving a conversion efficiency of 26.1%. Once again break through the 25.7% conversion efficiency created in April this year.

Up to now, Jingke Energy has broken the world record for battery efficiency and module power for a total of 20 times. In particular, the leading accumulation in the field of N-type TOPCon has broken the world record of N-type TOPCon battery for 6 times in the past 2 years. According to the official introduction, the maximum production power of Tiger Neo series components based on N-type TOPCon technology independently developed by Jingke Energy has exceeded 600W. In the same size of the module version, the current N-type Tiger Neo series components can have more than 20 watts higher power than P-type components on single-chip components, directly increase the power by at least 3.7%, and will bring customers at least 3% power generation gain under the same installed capacity.

According to the Kechuangban Daily, compared with the traditional P-type battery, N-type battery has the advantages of high conversion efficiency, high double-sided rate, low temperature coefficient, almost no light decay, good weak light effect and so on, but the manufacturing process is complex and the cost is higher. it is generally regarded as the next generation battery technology in the industry. TOPCon battery technology is one of the mainstream technology routes of N-type battery. in terms of theoretical limit conversion efficiency, the limit efficiency of HJT, TOPCon and perovskite single-layer batteries is 27.5%, 28.7% and 31%, respectively.

CTOnews.com learned that the agency pointed out that 2022-2023 is a big year for photovoltaic cell production expansion, and TOPCon will become the mainstream route of battery expansion in 2022-2023.

According to public data, Jingke Energy was founded in 2006 and listed on the New York Stock Exchange in 2010. as one of the few photovoltaic manufacturers in the world with vertically integrated industry chain, Jingke Energy business covers high-quality silicon ingots and wafers. Battery chip production and efficient single polycrystal photovoltaic module manufacturing.
