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 […]

New Operating Method Improves Wind Turbine Farm Output
August 16, 2022 | Leave a Comment
Both MIT and CalTech have press releases out explaining research that could increase wind turbine output by more than 1% up to 3%. The new technology is based on an algorithm that forces individual turbines to coordinate with the others thus boosting the total output. The new approach models the wind flow of the entire […]
