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.

The race for space solar

The space economy could be worth as much at $2 trillion by 2040 – according to a recent report by professional services provider PwC. The cisLunar orbit, between the earth and the moon, is particularly promising. But all of it requires power and, as it has for decades, that means PV – and both the technology and supplier landscape for orbital solar is diversifying. Eternal Sun | WAVELABS‘ Pepijn Veling reports from a series of events the company has attended across the country, on what is a fast-evolving technology and business landscape.
