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.
Testing validates silicon-based technology for next-gen green hydrogen systems
Australian start-up Siltrax is targeting commercial trails of its novel hydrogen fuel cell technology after testing showed its silicon-based bipolar plates deliver twice the power output of conventional metal and graphite materials.

China moves to curb overcapacity in PV industry with mandatory energy consumption standards
China has introduced mandatory national standards tightening energy consumption and efficiency requirements across the PV value chain, from polysilicon to modules and inverters. The rules, effective Jan. 1, 2027, are expected to reshape manufacturing, procurement and project selection toward higher-efficiency, lower-energy-intensity products.
