The 2023 XBC Battery and Component Technology Forum will be held in Xi’an on October 25-26. BC stands for back contact battery technology, which is a platform-type battery structure that can be called “both beautiful and effective.” It is characterized by no grid lines on the front of the battery and no metal electrodes to block it, maximizing the use of incident light, reducing optical losses and improving conversion power generation efficiency, thereby reducing photovoltaic electricity costs. As a universal platform technology, it can be combined with composite technologies such as PERC, HJT, and TOPCon to form various technical routes such as HPBC, HBC, and TBC. It continuously absorbs the process advantages and passivation technologies of other technical routes to continuously improve conversion efficiency and prospects. unlimited.
BC batteries have no reflection loss when exposed to light, and the battery conversion efficiency is high and the power generation per unit area is higher. The mass production efficiency of the standard version of LONGi HPBC batteries exceeds 25%. The power generation performance of Hi-MO6 modules equipped with this technology is 6%-10% higher than that of traditional modules, and the power generation efficiency is significantly improved.
Photovoltaic modules based on BC cell technology have no grid lines on the front, integrate life aesthetics and conform to the aesthetic trend of the times, and explore the possibilities of industrial aesthetics, especially to meet the diverse needs of distributed users, and greatly expand the application scenarios of photovoltaic module products.
Conference name: 2023 XBC Battery and Component Technology Forum

XBC (back contact battery technology) is a platform-type battery structure with no metal electrodes blocking the front of the battery, maximizing the use of incident light and reducing optical losses, thereby improving power generation efficiency. As a general platform technology, XBC can be combined with technologies such as PERC, TOPCon and HJT to form multiple technical routes such as HPBC, TBC and HBC. It will continue to absorb the process advantages and technological progress of other routes to continuously improve its competitiveness.
XBC type batteries are not blocked by grid lines on the front and have beautiful module appearance. They especially meet the diverse needs of distributed users and have advantages in scenarios such as household and industrial and commercial rooftops.
At the same time, the efficiency of XBC cells and components has great potential. The mass production efficiency of the standard version of LONGi HPBC batteries exceeded 25%; Tongwei's 2023 semi-annual report showed that the highest R&D efficiency of N-type TBC batteries reached 26.11%; the mass production efficiency of Aixu ABC batteries in 2023 reached 26.5%; in September 2023, Fujian Jinshi The HBC battery conversion efficiency reaches 27.42%. In addition, JA Solar, Trina, Jinko, Jolywood, Junda, etc. have also developed XBC battery technology.
