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.

Using a bird’s structural-color trick to color solar modules A scientific team had colored PV modules using quasi-ordered photonic pigments rather than conventional absorbing dyes. The technique was inspired by blue feather birds. The colored PV modules exhibited efficiencies that represent more than a 50% improvement over conventional pigments.
