PV Mag dives into the increasing research into silicon-free tandem solar cells at commercial, academic, and institutional labs in the US. These include all-organic, all-perovskite tandem combinations and cadmium telluride and copper indium gallium diselenide devices. They reference that multiple teams have announced lab-scale, all-thin-film cells with conversion efficiencies above 27% with the succession of tech being single junction, then perovskite-silicon tandem and then, eventually, all-thin-film.”
