Surface modification for more effective textured perovskite/silicon tandem solar cells

A coating of solar cells with special organic molecules could pave the way for a new generation of solar panels. As a research team reports in the journal Angewandte Chemie International Edition, this coating can increase the efficiency of monolithic tandem cells made of silicon and perovskite while lowering their cost because they are produced from industrial, microstructured, standard silicon wafers.
