Organometal halide perovskite based solar cells have recently emerged as one of the transformative photovoltaic technologies. Power conversion efficiency attained with CH3NH3PbI3 has now exceeded 15%, making them competitive with thin film PV technology. In this virtual issue we present a few recent articles that focus on the new methods and the physical insights into the operation of organometal halide perovskite solar cells.
