Study finds tandem PV has 30% lower environmental impact than crystalline silicon - pv magazine Global

A Spanish research team conducted a cradle-to-gate LCA of eight PV technologies across three generations, finding that tandem solar cells can outperform silicon-based systems in environmental terms due to higher efficiencies. However, cadmium telluride thin-film technologies still show the lowest overall impacts, while tandem systems require long lifetimes and improved stability to deliver clear sustainability advantages over established PV technologies.
