Solliance hits 29.2% efficiency on perovskite/silicon tandem solar cell

The Solliance consortium has built a solar cell in a four-terminal tandem configuration that combines a 17.8%-efficient highly near-infrared transparent perovskite cell with a prototype of an 11.4%-efficient c-Si interdigitated back contact silicon heterojunction cell developed by Panasonic.European Solliance Solar Research (Solliance), a consortium based in the Netherlands, said last week that researchers from three of its partners - the Netherlands Organisation for Applied Scientific Research (TNO), EnergyVille, and the Eindhoven University of Technology - have achieved a 29.2% power conversion ...
