Two new world records on perovskite/silicon tandem solar cells

— For the first time, an efficiency of 30% for perovskite-on-silicon-tandem solar cells has been exceeded thanks to a joint effort led by scientists at EPFL’s Photovoltaics and Thin Film Electronics Laboratory in partnership with the renowned innovation center, CSEM. Independently certified by the National Renewable Energy Laboratory (NREL) in the United States, these results are a boost to high-efficiency photovoltaics (PV) and pave the way toward even more competitive solar electricity generation.
