Core Viewpoint - The significant rise in silver prices has created substantial cost pressures for the photovoltaic (PV) industry, impacting the profitability of battery manufacturers and prompting companies to seek silver reduction technologies [3][9]. Group 1: Silver Price Impact - On December 10, silver prices reached a historic high, with London silver hitting $60.911 per ounce and COMEX silver reaching $61.435 per ounce, marking annual increases of over 110% and 109% respectively [3][8]. - The World Silver Association projects that global silver consumption for photovoltaics will reach 7,560 tons by 2025, doubling from three years ago and accounting for over 25% of total silver demand [3][9]. - The rising silver prices have severely impacted the midstream battery manufacturing segment of the PV industry, with silver paste costs exceeding 30% of the total cost of TOPCon210RN battery cells and over 50% of non-silicon costs [3][9]. Group 2: Supply Chain Pressures - The limited ability of battery manufacturers to pass on rising costs has led to significant erosion of profit margins in the intermediate processing stages, increasing the risk of losses [3][9]. - The World Silver Association anticipates a global silver supply-demand gap of 3,659 tons by 2025, equivalent to four months of global production [3][9]. Group 3: Technological Innovations - In response to these challenges, PV companies are actively pursuing technological breakthroughs to reduce silver usage. For instance, Shanghai Aiko Solar Energy Co., Ltd. has developed copper interconnection technology to mitigate costs [4][9]. - Longi Green Energy Technology Co., Ltd. has published research demonstrating a silver-free metallization technology that has achieved a solar cell efficiency of over 27%, with plans to further integrate equipment, materials, and processes [5][10]. - The silver reduction technology is progressing steadily, with expectations for small-scale production of TOPCon silver-copper paste in the first quarter of next year and potential small-scale applications of pure copper paste by the third quarter [5][10]. - However, there are concerns regarding the reliability of low-silver pastes, as any failure in the encapsulation barrier could lead to increased resistance and reduced efficiency, affecting the overall quality and lifespan of solar power systems [5][10].
