Researchers Transform Old Lead Bullets into Solar Panel Components
Researchers from the Jülich Research Centre in Erlangen, Germany, have successfully converted centuries-old lead bullets into lead iodide, a key component for perovskite solar panels. The team sourced these bullets from eBay, dating back to the 16th and 17th centuries, and processed them into high-purity lead iodide powder. This powder was then used to grow perovskite crystals, which are integral to the production of cost-effective and energy-efficient solar panels. The process involved washing and melting the bullets, followed by dissolving them in a solvent mixture and applying an electrical current. This innovative approach demonstrates the potential of repurposing toxic legacy waste into resources for clean energy.
