  • Perovskite Solar Cells: 2026 Procurement Essentials, Stability Hurdles and Scale-Up Outlook

    Perovskite solar cells (PSCs) have become one of the most watched directions in photovoltaic materials, thanks to their high theoretical efficiency, low manufacturing cost and potential for flexible/tandem applications. This article outlines the core materials, procurement essentials, stability bottlenecks and commercialization timeline for materials buyers and process engineers.

    Why Perovskites Matter

    • Single-junction theoretical efficiency ceiling is around 33%; tandem (perovskite/silicon) cells can exceed 30% in production.
    • Low-temperature solution processing keeps capex below conventional crystalline silicon and suits large-area coating and roll-to-roll manufacturing.
    • Tunable bandgap enables differentiated use cases: BIPV, flexible modules, automotive and space photovoltaics.

    Core Materials to Specify

    1. Perovskite precursors: lead halides (PbI₂, PbBr₂) and organic ammonium salts (FAI, MAI, CsI). Specify purity ≥99.99% and audit metal impurities and residual moisture.
    2. TCO substrates: FTO, ITO and similar; watch sheet-resistance uniformity and haze.
    3. Charge-transport layers: Spiro-OMeTAD, SnO₂, NiOₓ and others; qualify on carrier mobility and thermal stability.
    4. Encapsulation: moisture/oxygen barrier films and glass; water vapor transmission rate (WVTR) is the key metric.

    Stability: The Procurement Gate

    Damp heat (85°C/85% RH), UV exposure and thermal cycling are the dominant degradation modes. Lead-leakage compliance is equally critical—especially for EU-bound modules—so verify encapsulation integrity against relevant environmental regulations. Request accelerated-aging reports following the IEC 61215 route.

    Suppliers and Commercialization Pace

    Through 2026, multiple 100 MW-class pilot lines are coming online, and perovskite/silicon tandem modules are entering small-batch delivery. Prioritize suppliers with pilot-delivery records and third-party certification; validate in small batches before scaling.

    Procurement Checklist

    • Define efficiency and stability targets;
    • Lock precursor purity and TCO specs;
    • Validate encapsulation and aging data;
    • Pilot-import and track batch consistency.

    Perovskites remain early in commercialization, but the materials system is now well defined. Establishing material standards and verification workflows early is the decisive step to capture the technology window.

  • 钙钛矿太阳能电池：2026 采购要点、稳定性挑战与产业化前景

    钙钛矿太阳能电池（PSC）凭借高理论效率、低制造成本与柔性/叠层应用潜力，已成为光伏材料领域最受关注的方向之一。本文面向材料采购与工艺工程读者，梳理核心材料、采购要点、稳定性瓶颈与产业化节奏，帮助采购端提前建立标准。

    一、为什么值得关注

    • 单结理论效率上限约 33%，与晶硅叠层后量产效率有望突破 30%。
    • 低温溶液工艺，资本开支低于传统晶硅，适合大面积涂布与卷对卷制造。
    • 带隙可调，适配 BIPV、柔性组件、车载与空间光伏等差异化场景。

    二、采购关注的核心材料

    1. 钙钛矿前驱体：铅卤化物（PbI₂、PbBr₂）与有机铵盐（FAI、MAI、CsI）。纯度建议 ≥99.99%，重点核查金属杂质与残留水分。
    2. 透明导电氧化物（TCO）衬底：FTO、ITO 等，关注方阻均匀性与雾度指标。
    3. 电荷传输层材料：Spiro-OMeTAD、SnO₂、NiOₓ 等，关注载流子迁移率与热稳定性。
    4. 封装材料：阻水阻氧胶膜与玻璃盖板，水汽透过率（WVTR）是核心指标。

    三、稳定性：采购必须把关

    湿热（85℃/85% RH）、紫外与热循环衰减是主要失效模式。铅泄露合规同样关键，尤其面向欧盟出口时，应关注封装完整性与相关环保法规。建议要求供应商提供基于 IEC 61215 路线的加速老化测试报告。

    四、供应商与产业化节奏

    2026 年多条百兆瓦级中试线陆续落地，钙钛矿/晶硅叠层组件开始小批量交付。采购建议优先选择具备中试交付记录与第三方认证资质的供应商，先小批量验证再规模导入。

    五、采购清单小结

    • 明确效率与稳定性目标；
    • 锁定前驱体纯度与 TCO 规格；
    • 验证封装方案与老化数据；
    • 小批量导入并跟踪批次一致性。

    钙钛矿尚处产业化早期，但材料体系已逐渐清晰。采购端提前建立材料标准与验证流程，是抢占技术窗口期的关键一步。

  • 2026-09-08 Price Trend Daily Report

    2026-09-08 Price Trend Daily Report

    Price Overview

    Material Current Price Range WoW Trend
    PTFE Resin ¥32,000–48,000/t (general); electronic grade ~¥150,000/t +1.5% Firm / range-bound up
    PEEK Resin Domestic neat ¥200–400/kg; Imported ¥800–1,500/kg +1.0% Stable with mild upside
    Carbon Fiber T300(12K) ¥85–95/kg; Large-tow ¥72–80/kg +1.0% Bottoming, stabilizing
    PI Film Standard ¥20–50/m²; High-performance ¥80–200/m² 0% Stable (high-end tight)
    Specialty Ceramic Raw Materials ZrO₂ powder ¥18,000–33,500/t; Al₂O₃ ¥3,400–3,900/t +2.5% Divergent (Zr up, Al steady)

    Key Movements

    • Zirconia (specialty ceramics): Sinocera (Guocai) raised zirconia powder prices 10%–40% from July 27. Upstream zircon sand remains elevated (¥11,900–12,500/t) as overseas miners curb output and tighten China quotas; yttria surged on rare-earth export controls, and PCB/solid-state-battery grinding-media demand expanded — a triple driver making this the clearest gainer of the period.
    • PTFE Resin: +1.5%. Protected fluorspar mining and tight anhydrous HF support costs; producers are holding prices up. NVIDIA Rubin Ultra orthogonal backplanes add high-end electronic-grade demand, but downstream just-in-time buying and new capacity cap gains — a cost-push, range-bound uptrend.
    • PI Film: After Kaneka’s +20% list-price hike in April, electrical-grade prices stabilized from August (mono-axial ¥120/kg, bi-axial ¥180/kg, flat MoM). High-end electronic/semiconductor grades remain supply-tight with high import dependence and firm pricing.
    • Carbon Fiber: Bottom confirmed. Toray raised prices 10%–20% and Jilin Chemical Fiber followed early in the year, but high industry inventory and new capacity from Zhongfu Shenying cap the rebound — overall bottoming and stabilizing.
    • PEEK Resin: Humanoid robots, EVs, medical and aerospace demand keep expanding; domestic substitution caps mid/low-end prices while high-end holds firm — stable with mild upside.

    Impact Analysis

    • Procurement cost: Rising zirconia and PTFE costs flow directly into structural ceramics, seals, anti-corrosion linings and grinding media; related purchasing budgets should be raised 5%–10%.
    • Supply chain: Fluorochemical and zirconia supply is tight with extended lead-time risk; carbon fiber and PEEK are amply supplied with stronger buyer leverage. High-end PI film is import-concentrated (DuPont, Kaneka, SKC) — disruption risk outweighs price risk under geopolitical friction.

    Action Recommendations

    • Lock in prices: PTFE resin and zirconia powder — uptrends are clear; sign long-term agreements or lock orders early, and secure Q4 zirconia volume now.
    • Wait and see: Carbon fiber (high inventory, weak rebound — wait for better pricing) and PEEK (domestic substitution pressures prices — buy in batches to average cost).
    • Watch: High-end electronic-grade PI film is supply-tight; lock critical-project volumes and build dual sourcing.

    重点变动

    • 氧化锆（特种陶瓷）：国瓷材料自7月27日起上调氧化锆粉体价格10%–40%。上游锆英砂受海外矿商控产保价、对华配额收紧影响维持高位（11,900–12,500元/吨）；氧化钇受稀土出口管制而暴涨，PCB与固态电池研磨介质需求扩容，三重驱动下成为本期涨幅最明确的品种。
    • PTFE树脂：+1.5%。萤石保护性开采、无水氢氟酸供应偏紧推升成本，行业联合挺价；NVIDIA Rubin Ultra正交背板带来高端电子级增量，但下游按需采购与新产能释放压制涨幅，呈成本推动型震荡偏强。
    • PI薄膜：经历4月Kaneka全系列提价20%后，8月以来电工级价格企稳（单拉120元/kg、双拉180元/kg，环比持平）；高端电子级/半导体级仍供需偏紧、进口依赖度高，价格坚挺。
    • 碳纤维：确认触底。年初东丽提价10%–20%、吉林化纤跟涨，但行业库存仍高、中复神鹰等新增产能释放，反弹乏力，整体筑底企稳。
    • PEEK树脂：人形机器人、新能源、医疗、航空航天需求持续扩容，国产替代加速压低中低端价格而高端维持坚挺，稳中偏强。

    影响分析

    • 采购成本：氧化锆、PTFE成本上行将直接传导至结构陶瓷件、密封件、防腐内衬、研磨介质等，相关物料采购预算建议上调5%–10%。
    • 供应链：氟化工与氧化锆供给端偏紧，交期存在延长风险；碳纤维、PEEK供应充裕，议价空间较大。高端PI薄膜进口集中（杜邦、钟渊、SKC），地缘扰动下断供风险高于价格风险。

    行动建议

    • 建议锁价：PTFE树脂、氧化锆粉体——涨价趋势明确，尽早签订长协或锁单，氧化锆建议锁定Q4用量。
    • 建议观望：碳纤维（库存高、反弹乏力，等待更优价位）、PEEK（国产替代压价，分批采购摊薄成本）。
    • 重点关注：高端电子级PI薄膜供应偏紧，关键项目建议锁定用量并建立双源采购。

  • New Materials Policy Monitoring Daily Report (2026-09-08)

    New Materials Policy Monitoring Daily Report

    Date: September 8, 2026 (Tuesday)
    Scope: EU REACH SVHC / US EPA TSCA / China GB Standards
    Overall: No major sudden policy change detected today. September is a peak period for standards taking effect in multiple jurisdictions; two time-sensitive items require priority action.

    1. China GB Standards　Risk Level: Medium

    • Effective September 1, 2026, 443 national standards entered into force, including 59 mandatory standards, 375 recommended standards, and 9 food-safety standards.
    • Key new-materials standards:
      • GB/T 47195—2026 “Additive manufacturing — Specification for aluminum alloy and composite components by laser powder bed fusion” (effective Sep 1)
      • GB/T 36972—2026 “Performance specification for lithium-ion batteries of electric bicycles” (replaces the 2018 version, effective Sep 1)
      • New standards released for PAN-based oxidized fiber, marine high-strength crack-arrest steel plates, etc.
    • State Administration for Market Regulation: over 1,400 national standards for emerging industries released in 2026 YTD, with the new-materials sector exceeding 300 standards.
    • Food-contact materials: GB 4806.10—2025 “Determination and migration of phthalates in food-contact materials” took effect September 2, 2026.

    Impact: The September 1 batch affects new materials, Li-ion batteries, food-contact materials, and protective equipment — all relevant to exports. Mandatory standards (e.g., protective equipment GB 5725—2025) create market-access and procurement-elimination risk for non-compliant products.

    Recommended Actions:

    1. Immediately reconcile in-production / on-sale products against the 59 mandatory standards to confirm applicability;
    2. Update technical files and test reports for Li-ion batteries to GB/T 36972—2026;
    3. For food-contact material producers, verify compliance with GB 4806.10—2025 migration limits;
    4. Maintain a “standards implementation calendar” to avoid missing the September batch.

    2. US EPA TSCA　Risk Level: Medium (imminent)

    • The Multi-Walled Carbon Nanotubes (MWCNT) SNUR final rule was published July 24, 2026 and becomes effective September 22, 2026 (substance under a TSCA Section 5(e) order, used as a battery-manufacturing additive). Effectiveness triggers TSCA Section 13 import certification and Section 12(b) export notification obligations.
    • SNUR batch (24-5.5e) final rule becomes effective October 26, 2026; formally promulgated September 9 (tomorrow).
    • PFAS 8(a)(7) reporting under TSCA begins January 31, 2027.

    Impact: The MWCNT SNUR takes effect in roughly two weeks. Battery, semiconductor, display-material, and coating companies using nanomaterials must prepare import certification and export notifications in advance.

    Recommended Actions:

    1. For battery/material products containing MWCNT, confirm the TSCA Section 13 import-certification filing path before September 22;
    2. Reconcile supplier declarations; distinguish the already-effective P-22-163 from the still-proposed P-23-105 (do not conflate the two);
    3. Monitor the September 9 SNUR (24-5.5e) final text and assess whether covered substances touch your US business.

    3. EU REACH SVHC　Risk Level: Low (baseline monitoring)

    • The most recent ECHA-confirmed update was February 4, 2026, adding n-Hexane (CAS 110-54-3) and Bisphenol AF (BPAF) and its salts; the Candidate List now totals 253 entries.
    • No new ECHA official SVHC list update was published today (Sep 8). The mid-year (typically June) update remains to be verified on the ECHA website.

    Baseline obligations (for reference): When an SVHC exceeds 0.1% w/w in an article, suppliers must fulfill REACH Article 33 supply-chain communication duties; if annual export volume exceeds 1 tonne, notify ECHA; and complete SCIP database notification.

    Recommended Actions:

    1. Maintain SVHC screening; focus on n-Hexane and BPAF presence in formulations and finished goods;
    2. Continuously monitor the ECHA website for the mid-year update and any newly added substances;
    3. Improve supply-chain substance declarations (supplier SDS, composition disclosure) to reserve time for SCIP filings.

    Priority Actions

    ① Verify compliance with China’s 59 mandatory national standards (already in force); ② Prepare MWCNT SNUR import certification for the US (effective Sep 22). Both are time-sensitive — recommend initiating within this week.

    1. 含MWCNT的电池/材料产品，9月22日前确认TSCA第13条进口认证申报路径；
    2. 梳理供应商声明，区分已生效的P-22-163与仍在拟议状态的P-23-105（两者不可混淆）；
    3. 关注9月9日SNUR(24-5.5e)正式文本，评估覆盖物质是否涉及本企业在美业务。

    三、欧盟REACH SVHC　风险等级：低（基线监控）

    • 最近一次经ECHA官方确认的更新为2026年2月4日，新增正己烷（n-Hexane, CAS 110-54-3）与双酚AF及其盐类（BPAF），候选清单总数达253项。
    • 今日（9月8日）未发现ECHA官方发布新的SVHC清单更新；年中（通常6月）更新尚待ECHA官网核实确认。

    基线义务（供参考）：物品中SVHC含量>0.1% w/w时，供应商须履行REACH第33条供应链信息传递义务；年出口量>1吨须向ECHA通报；并须完成SCIP数据库通报。

    行动建议：

    1. 维持SVHC筛查机制，重点排查正己烷、BPAF在配方与成品中的使用情况；
    2. 持续监控ECHA官网，确认年中更新是否已发布及新增物质清单；
    3. 完善供应链物质声明（供应商SDS、成分披露），为SCIP通报预留时间。

    优先处置项

    ① 中国59项强制性国标符合性核查（已生效）；② 美国MWCNT SNUR进口认证准备（9月22日生效）。两项均为时间敏感事项，建议本周内启动。
