1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints of the Report - The silicon market is characterized by weak supply and demand, with limited improvement on the demand side. The industrial silicon market remains in an oversupply situation, which may put pressure on the upper limit of the market. Attention should be paid to the pressure level of 9,300 - 9,500 yuan/ton. For polysilicon, the downstream replenishment willingness is limited, and there is significant pressure for the spot price to rise further, which restricts the upward space of the market [1]. - For industrial silicon, the trading strategy is to conduct range - bound operations. For polysilicon, before the implementation of supply - side reform policies, investors can try to go long on dips with a light position [1]. 3. Summary by Relevant Catalogs Industrial Silicon - **Price**: The closing price of the futures main contract was 9,020 yuan/ton, down 1.37% from the previous day. The basis (East China 553 - futures main contract) was 330 yuan/ton, an increase of 125 yuan/ton. The average prices of various grades of industrial silicon in different regions remained unchanged [1]. - **Supply**: Southwest production areas are entering the high - cost dry season. Some silicon enterprises stopped furnaces and production at the end of October, resulting in a significant decline in the operating rate. In November, the industrial silicon output is expected to drop below 400,000 tons. Although the number of open furnaces in the north increased steadily, the overall supply decreased [1]. - **Demand**: Polysilicon enterprises maintained production cuts, organic silicon enterprises were mostly in a state of reduced load or maintenance, and silicon - aluminum alloy enterprises purchased on demand. The overall willingness of downstream enterprises to stock up at low prices was limited [1]. - **Investment Strategy**: Conduct range - bound operations. Pay attention to the pressure level of 9,300 - 9,500 yuan/ton and continuously monitor industrial policy changes and silicon enterprise production dynamics [1]. Polysilicon - **Price**: N - type dense material remained unchanged at 51 yuan/kg; N - type re -投料 price rose 0.29% to 52.30 yuan/kg; N - type mixed material and N - type granular silicon remained unchanged. The closing price of the futures main contract was 54,045 yuan/ton, down 0.28% from the previous day [1]. - **Supply**: Silicon material enterprises maintained a production - cut state, and some silicon material factories may have new production capacity put into operation. After offsetting, the output in October still increased slightly, and the output in November is expected to drop to about 120,000 tons [1]. - **Demand**: The polysilicon market transactions were light, with few new transactions. Downstream enterprises were highly resistant to high - priced resources, and the market was waiting for industry policy guidance [1]. - **Investment Strategy**: Before the implementation of supply - side reform policies, try to go long on dips with a light position. Pay attention to the implementation of the polysilicon platform and the evolution of macro - sentiment [1]. Other Information - On November 12, the ceremony for the full grid - connection of the 35 - megawatt solar photovoltaic power station equipment project aided by China to Cuba was held. The project includes 7 photovoltaic power stations, which will increase Cuba's clean power supply capacity and save about 18,000 tons of imported fuel annually [1]. - On November 6, the first - phase 102.56 - megawatt power generation unit of the Puxi Photovoltaic Project of the Dadu River Ashui (New Energy) Company under the National Energy Group was successfully connected to the grid, marking the commissioning of the first - phase components of the group's highest - altitude centralized photovoltaic power station [1].

Core Viewpoint - The increasing interest in perovskite solar cells is driven by the realization that investments in crystalline silicon are often unprofitable, making perovskite the "only choice" for companies in the photovoltaic market [3][4]. Industry Development - Over the past three years, major photovoltaic companies and energy firms have entered the perovskite sector, with expectations for mass production to begin in 2025. Companies like GCL-Poly and others are establishing GW-level production lines [4][6]. - GCL-Poly has set up a GW-scale production base for perovskite tandem modules, aiming for a 500MW production line by the end of the year [4]. - Other companies, including Renshou Energy and Xina Solar, are also planning to launch 500MW production lines within the year [4]. Technological Advancements - The theoretical efficiency limit for perovskite tandem cells is 43%, which is seen as a mainstream technology to surpass the efficiency limits of single crystalline silicon cells [5]. - Companies like LONGi Green Energy and Tongwei Co. are investing in perovskite-silicon tandem cell research, with some already establishing MW-level production lines [5][6]. Market Opportunities - Many domestic perovskite companies are targeting applications in areas like streetlights and carports, aiming to penetrate markets that crystalline silicon cannot easily cover [8]. - GCL-Poly is focusing on directly replacing crystalline silicon components in photovoltaic power stations, with a recent project in Qinghai utilizing perovskite components [9][10]. Cost and Efficiency Considerations - The production cost of perovskite is theoretically lower than that of crystalline silicon, but current production costs remain high due to limited capacity [11]. - The cost of components in photovoltaic systems is decreasing in significance, with balance of system (BOS) costs becoming more dominant [10]. Competitive Landscape - The photovoltaic industry has seen a shift from PERC to TOPCon and other technologies, leading to a situation where many companies are experiencing losses due to oversupply [13]. - The complexity of perovskite production may prevent it from entering a similar "involution" phase as seen with crystalline silicon technologies, as each new formulation represents a new product [14][15].
