In a joint effort between Pavia University (Italy) and the Center for Advancing Electronics Dresden at Technische Universität Dresden (Germany), researchers developed a novel method to fabricate lead halide perovskite solar cells with record efficiency – publication in the journal Science Advances

Metalenses are ultrathin, flat surfaces that use nanostructures to focus light. They have attracted tremendous attention because they can overcome limitations of conventional bulky, curved and heavy refractive optical lenses and they are poised to revolutionize everything from microscopy to cameras, sensors, and displays.
