IEA-PVPS 分析光伏材料需求：银铜铟锡供给压力与回收前景
Keeping pace with PV growth
IEA-PVPS Task 12 报告分析了硅基光伏从当前 3 TW 扩张至 2050 年 29–75 TW 的材料流。2025–2050 年累计银需求约 5 万至 60 万吨，铜需求 1.45 亿至 2.8 亿吨，其中约四分之三来自电缆；铟需求约 1 万至 30 万吨，锡需求约 100 万至 300 万吨。报告称退役组件回收在 2050 年前仅能覆盖累计需求的约 15%–20%。

As global PV deployment moves toward tens of terawatts, demand for copper, aluminum, silicon and other key materials will grow substantially. However, new analysis shows that future material requirements will depend not only on how much PV is installed, but also on technological developments – from copper metallization and thinner wafers to new cell architectures and recycling.
