Photovoltaic (PV) cells, which can generate energy from the sun, could be very useful in tackling the current environmental crisis. Perovskite PV cells, cells made of metal halide perovskite semiconductors, have recently proved to be particularly promising, as researchers have managed to improve their power conversion efficiencies substantially, from 3.8% all the way to 25.2%.
