Laser-based PV recycling method demonstrates high silicon, silver recovery

Researchers at the Netherlands Organisation for Applied Scientific Research (TNO) have outlined a nanosecond laser-assisted recycling process, known as LARS, designed to open silicon PV modules while preserving high-value silicon and silver fractions for recovery. Conventional recycling routes such as shredding recover bulk materials like glass and aluminum efficiently but tend to fragment or contaminate the smaller, higher-value silicon and silver fractions, which the researchers said make up only a small share of a module's mass but the bulk of its recoverable value. The LARS process instead ...
