Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) researchers reported a new world record for tandem solar cells consisting of a silicon bottom cell and a perovskite top cell. The new tandem solar cell converts 32.5 percent of the incident solar radiation into electrical energy. The certifying institute European Solar Test Installation (ESTI) in Italy measured […]

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 […]

Stanford University researchers have stacked perovskites onto a conventional silicon solar cell dramatically improving the overall efficiency of the cell. Study co-author Michael McGehee, a professor of materials science and engineering at Stanford said, “We’ve been looking for ways to make solar panels that are more efficient and lower cost. Right now, silicon solar cells […]
