Core Insights - The silver price surge is significantly impacting the photovoltaic (PV) industry in China, leading to major companies like Heraeus exiting the market due to reduced profit margins [1][6]. Group 1: Silver Price Impact - As of December 1, the spot silver price reached a historic high of $57.7 per ounce, with a year-to-date increase of over 90%, outpacing gold [2]. - Silver paste constitutes approximately 12% of the total cost of PV modules and over 50% of the non-silicon costs in battery cells [2]. - The supply-demand gap for silver is projected to remain significant, with an estimated shortfall of about 3,660 tons by 2025 [2]. Group 2: Technological Innovations - The rising silver prices have prompted a "silver reduction revolution" in the PV manufacturing sector, with companies optimizing processes to reduce silver consumption by nearly 80% over the past three years [3]. - The silver consumption for TOPCon cells is expected to decrease from 90-95 mg/W in 2024 to 80-85 mg/W by the third quarter of 2025 [3]. - Companies like Tongwei have successfully reduced silver usage in HJT cells by nearly 80% through innovative techniques [3]. Group 3: Market Dynamics and Challenges - The PV manufacturing industry faces a critical decision between adopting cheaper but less efficient silver-coated copper paste or waiting for the more advanced but not yet mature electroplating copper technology [6]. - The silver paste sector is under pressure due to volatile silver prices and extended payment terms from downstream customers, leading to significant profit margin squeezes [6]. - Domestic silver paste companies are also struggling, with companies like Dike experiencing a 70.03% year-on-year decline in net profit for the first half of 2025 [6]. Group 4: New Market Opportunities - The technological shift in silver usage is creating new market opportunities, with the market for new types of pastes expected to exceed 15 billion yuan by 2030 [6]. - Companies in the upstream supply chain, such as Guangxi Jianxing, are breaking foreign monopolies by producing ultra-fine silver powder at a significantly lower cost compared to imported alternatives [7]. Group 5: Industry Outlook - The international precious metals market is facing historic structural pressures, with the PV industry closely monitoring silver price fluctuations [8]. - The timeline for technological iterations in the PV sector is being compressed from several years to just one or two years, making silver reduction a critical survival challenge for all PV companies [8].

Summary of the Conference Call Industry Overview - The photovoltaic (PV) industry is experiencing severe overcapacity, with nominal capacities in various segments approximately double the expected module production of 650-700 GW for 2025, while nominal capacities across the supply chain exceed 1,200 GW [2][4] - The supply of auxiliary materials such as encapsulants and glass is projected to be between 800-900 GW annually, with glass supply being slightly better due to ongoing capacity construction [2][4] Key Points on Silicon Material Market - The end of the 430 and 531 rush has led to a decline in module production, causing silicon material prices to drop significantly. The price of n-type granular silicon has fallen to 34,500 CNY/ton (including tax), with the non-tax average between 30,000-33,000 CNY/ton [2][5] - Most companies are currently operating at a loss, with only a few able to cover cash costs. As a result, the silicon material industry plans to reduce monthly production from approximately 100,000 tons to 83,000 tons, resulting in an industry operating rate of only about 30% [2][5] Inventory and Production Outlook - Silicon material inventory has been high at around 500,000 tons but has recently decreased to about 400,000 tons due to increased module production. If production remains at 100,000 tons/month, inventory could normalize by mid-2026 [6] - If production drops to 85,000 tons/month starting in July, normalization could be achieved by the end of 2025 [6] Cost Reduction Strategies - In the context of profit pressure in the PV industry, reducing silver paste costs is critical. Silver paste accounts for 12% of module costs and 39% of battery costs, second only to glass and aluminum frames [2][7] - Copper substitution is a primary method for cost reduction, with technologies including silver-coated copper, high-copper paste, pure copper paste, and electroplated copper [2][7] Copper Diffusion and Efficiency - Copper has a higher diffusion coefficient than silver in silicon wafers, which can negatively impact battery efficiency. To mitigate this, copper powder must be coated, and a silver seed layer is placed between the copper paste and silicon wafer to prevent direct contact [8] - This approach reduces contact resistance and promotes copper paste sintering, with current market solutions primarily using a silver seed layer in conjunction with copper paste [8] Market Solutions for Copper Paste - Two main copper paste solutions are being promoted: high-copper paste developed by Dike and pure copper paste developed by Polymeric. Dike's high-copper paste uses silver as a coating material and is priced at 4,000-5,000 CNY/kg, offering a cost saving of approximately 0.5 cents per watt [9][10] - Polymeric's pure copper paste, which uses non-silver materials for coating, is priced at 2,500-3,000 CNY/kg and also provides similar cost savings but requires specialized sintering furnaces [10] Market Adoption and Future Prospects - Both high-copper and pure copper paste solutions are being actively promoted in the market. High-copper paste is progressing rapidly due to its reliability in preventing diffusion risks, with expected shipments reaching several hundred tons by 2026 [11] - The higher processing barriers for high-copper paste compared to traditional products may lead to significant performance elasticity, while the successful implementation of pure copper paste could yield even greater cost savings [11]

Investment Rating - The investment rating for the company is "Buy" and is maintained [8]. Core Views - The company reported a revenue of 4.056 billion yuan in Q1 2025, representing a year-on-year increase of 11%. However, the net profit attributable to the parent company was 35 million yuan, a significant decline of 80% year-on-year. The net profit after deducting non-recurring items was 65 million yuan, down 66.72% year-on-year [2][6]. Financial Performance - In Q1 2025, the company experienced a decrease in silver paste shipments due to weak battery component production, with the N-type TOPCon shipment ratio remaining stable. The company recorded a fair value loss of 40 million yuan, primarily due to fluctuations in silver futures prices. Additionally, the company made a cautious provision for credit impairment losses of 20 million yuan and reported other income of 61 million yuan, mainly from VAT rebates [12]. - The company is actively developing low-silver metallization technologies to adapt to future market changes, including a series of products transitioning from silver to copper. The N-type HJT battery low-temperature silver-coated copper paste product is expected to achieve large-scale shipments, and the company is also working on high-copper paste designs compatible with TOPCon and TBC production lines, with large-scale production anticipated in the second half of the year [12]. Market Position and Strategy - The company is focusing on reliable, mass-producible, and cost-effective solutions in response to industry cycles. It has established long-term cooperative development with leading customers for high-copper paste applications, particularly for TOPCon and TBC batteries, with expectations for large-scale production in the latter half of the year [12]. Financial Projections - The company forecasts total revenue of 19.44 billion yuan for 2025, with a projected net profit of 485 million yuan. The earnings per share (EPS) is expected to be 3.45 yuan [18].
