This record, once again validated in testing carried out by the Institute for Solar Energy Research (ISFH) in Hamelin, Germany, was achieved on M6 (274.5cm2) full-size monocrystalline silicon wafers, confirming the basis for industrialisation of the low-cost technology route for HJT cells, following ongoing research by LONGi’s R&D team. ![](https://blog.nastechsolar.com/hubfs/Imported_Blog_Media/Wechat_IMG_13089_3bb1558e29-Mar-25-2024-01-31-04-2443-PM.jpeg) Advanced surface passivation technology previously developed by the team was applied to the HJT cells, using low-cost indium-free targets to prepare transparent conducting oxide films. Process innovations enabled the cells to maintain a high conversion efficiency despite being completely indium-free. The high-efficiency HJT cells will effectively reduce dependence on indium resources in mass production and result in a significant reduction in costs. ![](https://blog.nastechsolar.com/hubfs/Imported_Blog_Media/new_record_for_p_type_HJT_2022032901_444db16c5a-Mar-25-2024-01-32-08-4289-PM.png) LONGi has now achieved overall leadership in a number of new high-efficiency cell technologies,such as n-type and p-type TOPCon and n-type and p-type HJT, continually pushing the limits for commercial use of solar energy applications to new levels. **About LONGi** Founded in 2000, LONGi is committed to being the world’s leading solar technology company, focusing on customer-driven value creation for full scenario energy transformation. Under its mission of 'Utilizing Solar Energy, Building a Green World' and brand philosophy of 'Steadfast and Reliable Technology Leadership', LONGi has dedicated itself to technology innovation and established five business sectors, covering [mono silicon wafers](https://www.longi.com/en/products/silicon/), cells and [modules](https://www.longi.com/en/products/modules/), [commercial & industrial distributed solar solutions](https://www.longi.com/en/solutions/residential/), [green energy solutions](https://www.longi.com/en/solutions/detail/eco-friendly-solar/) and [hydrogen equipment](https://www.longi.com/en/products/hydrogen/). The company has honed its capabilities to provide green energy and has, more recently, also embraced green hydrogen products and solutions to support global zero carbon development. [www.longi.com](https://www.longi.com/en/news/solarbutterfly-world-tour/www.longi.com) Share: [facebook-f icon](http://www.facebook.com/share.php?u=https://blog.nastechsolar.com/en/us/news/indium-free-hjt) [linkedin-in icon](http://www.linkedin.com/shareArticle?mini=true&url=https://blog.nastechsolar.com/en/us/news/indium-free-hjt) [twitter icon](https://twitter.com/intent/tweet?url=https://blog.nastechsolar.com/en/us/news/indium-free-hjt) [pinterest-p icon](http://pinterest.com/pin/create/link/?url=https://blog.nastechsolar.com/en/us/news/indium-free-hjt) [envelope icon](mailto:?body=https://blog.nastechsolar.com/en/us/news/indium-free-hjt) ## Related posts [![](https://blog.nastechsolar.com/hubfs/Imported_Blog_Media/indium_free_hjt_2022040101_595989659e.jpg)](https://blog.nastechsolar.com/en/au/news/indium-free-hjt?hsLang=en) ### [LONGi-LONGi achieves new world record for indium-free HJT cell efficiency](https://blog.nastechsolar.com/en/au/news/indium-free-hjt?hsLang=en) [![](https://blog.nastechsolar.com/hubfs/Imported_Blog_Media/indium_free_hjt_2022040101_595989659e-Mar-26-2024-05-44-40-3593-AM.jpg)](https://blog.nastechsolar.com/en/news/indium-free-hjt?hsLang=en) ### [LONGi-LONGi achieves new world record for indium-free HJT cell efficiency](https://blog.nastechsolar.com/en/news/indium-free-hjt?hsLang=en) [![](https://blog.nastechsolar.com/hubfs/Imported_Blog_Media/indium_free_hjt_2022040101_595989659e-Mar-26-2024-05-35-48-5511-AM.jpg)](https://blog.nastechsolar.com/en/in/news/indium-free-hjt?hsLang=en) ### [LONGi-LONGi achieves new world record for indium-free HJT cell efficiency](https://blog.nastechsolar.com/en/in/news/indium-free-hjt?hsLang=en) [![Home of Clean Energy](https://blog.nastechsolar.com/hs-fs/hubfs/Nastech%20logo-1.png?width=410&height=139&name=Nastech%20logo-1.png "Home of Clean Energy")](http://nastech.ae) **Pages** Home Services Portfolio About Contact FAQ Landing Page Thank You **Resources** Blog Watch a Demo Academy Webinars Product Changes Copyright © 2010 - 2026, NASTECH DMCC ```json { "@context" : "https://schema.org", "@type" : "BlogPosting", "author" : { "@type" : "Person", "name" : "Longi", "url" : "https://blog.nastechsolar.com/en/author/longi" }, "dateModified" : "2024-03-25T13:34:16.137Z", "datePublished" : "2023-10-17T20:00:00.000Z", "headline" : "LONGi-LONGi achieves new world record for indium-free HJT cell efficiency", "image" : [ "https://blog.nastechsolar.com/hubfs/Imported_Blog_Media/indium_free_hjt_2022040101_595989659e-Mar-25-2024-01-31-04-4997-PM.jpg" ], "mainEntityOfPage" : { "@id" : "https://blog.nastechsolar.com/en/us/news/indium-free-hjt", "@type" : "WebPage" }, "publisher" : { "@type" : "Organization", "logo" : { "@type" : "ImageObject", "url" : "https://blog.nastechsolar.com/hubfs/Nastech%20logo-1.png" }, "name" : "NASTECH DMCC" } } ``` ```json { "@context" : "http://schema.org", "@type" : "Article", "author" : { "@type" : "Person", "name" : [ "Longi" ], "url" : "https://blog.nastechsolar.com/en/author/longi" }, "datePublished" : "2023-10-17T20:00:00+0000", "description" : "Only days after setting a record of 25.47% for efficiency of its p-type HJT cells, LONGi has announced a new record of 25.40% for its indium-free HJT cells.", "headline" : "LONGi-LONGi achieves new world record for indium-free HJT cell efficiency", "image" : "https://23100838.fs1.hubspotusercontent-na1.net/hubfs/23100838/Imported_Blog_Media/indium_free_hjt_2022040101_595989659e-Mar-25-2024-01-31-04-4997-PM.jpg", "publisher" : { "@type" : "Organization", "logo" : { "@type" : "ImageObject", "url" : "https://cdn2.hubspot.net/hubfs/23100838/Nastech%20logo-1.png" }, "name" : "NASTECH DMCC" }, "url" : "https://blog.nastechsolar.com/en/us/news/indium-free-hjt" } ```
