🏭HJT供应商格局：Huasun公司在HJT组件领域保持领先地位，其最高效率产品在8月份达到23.18%。通威紧随其后，其他公司如REC和Grand Sunergy也推出了新的高效产品。

TaiyangNews TOP SOLAR MODULES Analysis 2024 looked into module efficiency development for different technologies - cell technologies – IBC, HJT, TOPCon, and PERC. Interdigitated Back Contact (IBC) modules achieved the highest efficiency improvement of 1.4% absolute over 2 years, as the top performers in solar module technology (See IBC Technology: Efficiency Leader With Limited Representation In 2024)The efficiency band for HJT has changed twice in the last 2 years. In 2024, the top efficiency increased from 23.02% at the beginning of the year to 23.18% in August, which remained the highest for HJT for the rest of the year. In 2023, both the upper and the lower limit improved simultaneously in September. While the top efficiency took a jump of close to 0.5% absolute from the year’s starting level of 22.53% to 23.02%, the lower limit was upped from 21.68% to 21.8%.As for the companies, Huasun retained its leadership as the top HJT product supplier, holding the top efficiency spot for the last 2 years. At the beginning of 2024, a 23.02% efficient module represented the company. Then in August, Huasun improved the efficiency of its top HJT commercial offering to 23.18%. Tongwei took the 2nd position with a marginally lower efficiency product of 23% throughout the year. The first change this year was the delisting of a 22.5% efficiency module from Canadian Solar (CSI), leaving the efficiency level solely to Risen. Then in July, REC commercialized its latest Alpha Pure-RX with an improved efficiency of 22.6%, replacing the previous 22.3% product. The last change to this technology stream was in October when China-based Grand Sunergy debuted on the list by providing proof of commercialization for its 22.86% HJT module. The products that remained unaltered during the course of 2024 were URECO’s 22.44% module, the 22.37% product from Akcome, Jinergy’s 21.85% module, and the 21.8% efficiency HJT module from Meyer Burger that represented the lower limit for this stream (see HJT Technology Trends In TOP SOLAR MODULES Analysis 2024).
