Solar panels deliver record-breaking efficiency – Archives Technologist.eu

All rooftop solar panels look pretty much the same from the outside: same size, same thickness and even the same installation system. But on the inside, the solar panels developed by EPFL spin-off Insolight stand apart. They deliver yields of 29% – nearly twice as much as the others currently on the market (which have yields of 17 to 19%). Insolight’s panels, which were recently tested by an independent lab, use a patented optical system that concentrates sunlight on a kind of miniature photovoltaic cell normally used in satellites
