Background

XBC (Back Contact Cell Technology) is a platform-based cell structure that features no metal electrode shading on the front side, maximizing the utilization of incident light and reducing optical losses, thereby improving power generation efficiency. As a versatile platform technology, XBC can be integrated with technologies such as TOPCon and HJT to form various technical routes like TBC, HBC and HTBC. It continuously absorbs the process advantages and technological advancements from other routes, enhancing its competitiveness.

XBC cells with no front fingers shading, offer aesthetically pleasing module appearances, particularly meeting the diverse needs of distributed users. They hold advantages in scenarios such as residential and commercial-industrial rooftops. In January 2025, Gold Stone's hybrid BC modules were certified by an authoritative institution with a bifaciality rate of 75.5%. Aiko's ABC module bifaciality rate increased from 70% at the end of 2023 to 75%, and is expected to reach 80% this year. In February 2025, Longi secured the largest centralized BC project in China, with a scale of 500MW, marking further recognition of BC technology in ground power station scenarios.

Meanwhile, XBC cells and modules have significant efficiency potential. Longi's HBC cell efficiency reached 27.30%, setting a new world record. In November 2024, Aiko's ABC module mass production and delivery efficiency reached 24.6%. The perovskite/hybrid BC four-terminal tandem solar cell developed by Gold Stone and Huaqiao University achieved a conversion efficiency of 34.61%. The significant advancements brought by 0BB technology in reducing silver paste consumption and improving cell efficiency will become mainstream in the XBC cell market. Additionally, companies like JA Solar, Tongwei, Trina, GCL, Jinko, Jolywood, and Jietai have also developed XBC cell technologies.

XBC cell and module production capacity is rapidly expanding. Due to strong promotion by industry leaders, the market share of XBC cells in 2024 has significantly increased compared to 2023, accounting for about 5%. Asiachem predicts that XBC cell and module production capacity will rapidly expand in 2025, bringing huge market opportunities for upstream and downstream technology, equipment and material suppliers in the industry chain.

3^rd XBC Cell & Module Forum 2025 will be held on May 15-16 in Jiaxing, Zhejiang, China. The conference will explore the PV market outlook and the competitive landscape of XBC, TOPCon and HJT cells, the application advantages of XBC modules in residential and commercial-industrial distributed scenarios, XBC cell production processes, key equipment and cost reduction paths, advanced conductive pastes and metallization technologies serving XBC cells, 0BB technology aiding XBC cost reduction and efficiency improvement, TBC, HBC, and HTBC technology R&D progress and efficiency enhancement potential, XBC cell bifaciality optimization and centralized power station application prospects, etc. This conference will provide ZOOM Global Online Participation and simultaneous interpretation in Chinese and English.
