Two teams of solar-power engineers, one led by a large group at Helmholtz-Zentrum Berlin für Materialien und Energie GmbH, the other led by a group at École Polytechnique Fédérale de Lausanne, has found two ways to improve the efficiency of solar cells by getting silicon and perovskite to work together better. Both teams have published papers in the journal Science outlining the details of their work and the results of their testing. Stefaan De Wolf and Erkan Aydin, with the King Abdullah University of Science and Technology, have published a Perspectives piece in the same journal issue outlining the work done by both teams.
