lead in solar

This quarter, pv magazine‘s UP Initiative focuses on lead – a toxic heavy metal that’s present in many PV technologies, and one that’s often mentioned in connection with hazardous substances across the green energy supply chain. We take a closer look at the issue and ask what it would mean for manufacturers to replace lead in their modules with more environmentally friendly materials.

Toxicologists are struggling to follow the pace at which perovskite solar cells race from laboratory test benches to factory production lines. While researchers continue to assess the health and safety risks stemming from the lead used at the core of these new materials, the startups commercializing them argue that established encapsulation techniques and sound recycling schemes are enough to safety-proof their potentially disruptive technology and offset broader environmental threats.
