Scientists turn end-of-life PV silicon into high-value silicon nitride

South Korean researchers have developed a method to upcycle silicon recovered from end-of-life PV modules into high-value silicon nitride (Si₃N₄). The process achieved recycled silicon purity of 99.95% through optimized milling, acid etching, and sedimentation before nitridation.
