@atomicmonkeyConclusion If cesium-based perovskite solar panels become the dominant technology, securing enough cesium will require a multi-pronged strategy that includes: Accelerating the development of new mining projects (e.g., Power Metals Corp and other emerging suppliers). Investing in recycling technologies for end-of-life solar panels. Exploring alternative perovskite formulations to reduce or eliminate cesium reliance. In the near term, companies with access to cesium-rich deposits (such as Power Metals Corp) stand to benefit tremendously. As an investor, it would be prudent to monitor developments in perovskite research, mining projects, and global cesium supply chains to capitalize on this potential bottleneck. If cesium remains critical and demand surges, its rarity could drive a supply-demand imbalance, making it one of the most strategically valuable elements of the renewable energy transition.
