光伏行业新技术专题研究：0BB技术有望带动相关设备、材料需求

Investment Rating - The report maintains a "Strong Buy" rating for the photovoltaic industry [1] Core Viewpoints - The 0BB (no busbar) technology is expected to drive demand for related equipment and materials, significantly reducing silver consumption and enhancing power output [5][14][17] - The commercialization of 0BB technology is progressing steadily, with major photovoltaic companies actively adopting various technical routes [4][40] - The 0BB technology opens up market opportunities for related equipment and materials, including string welding machines, ultra-fine welding ribbons, adhesives, and new membrane materials [5][68] Summary by Sections 1. Introduction to 0BB Technology - 0BB technology eliminates the main busbar, directly connecting the welding ribbon to the fine grid, which reduces silver paste consumption by over 40% and lowers component costs [14][17] - The technology allows for thinner silicon wafers and reduces the amount of encapsulant used, addressing issues like micro-cracking and improving product yield [22][23] 2. Market Opportunities Created by 0BB Technology - The demand for 0BB string welding machines is expected to exceed 10 billion yuan, with significant market value projected over the next three years [49][50] - The development of specialized 0BB welding ribbons and adhesives is crucial, as these components will replace traditional materials and meet the new technical requirements [5][68] 3. Investment Recommendations - Investors are advised to focus on leading companies in the 0BB-related sectors, including string welding machines, photovoltaic welding ribbons, adhesives, and new membrane materials [5][68]
