Scalable Path to Produce Perovskite Silicon Tandem Solar Cells

In a joint research effort, scientists from King Abdullah University of Science and Technology KAUST and Fraunhofer Institute for Solar Energy Systems successfully replaced spin-coating with blade-coating in the production of perovskite-silicon tandem solar cells. In a “hybrid route” combining evaporation and blade-coating to deposit perovskite solar cells on silicon bottom cells, they produced tandem solar cells with efficiencies approaching 28 percent. Their result opens a path to the large-scale production of this promising new solar cell technology.
