Perovskite Silicon Combined For Much Higher Solar Efficiency
October 25, 2022 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Tandem solar cells made of perovskite and silicon enable significantly higher efficiencies than silicon solar cells alone. By the end of 2021, teams at HZB (Helmholtz-Zentrum Berlin für Materialien und Energiehad) presented perovskite silicon tandem solar cells with an efficiency close to 30 percent. This value was a world record for eight months, a […]
