    Ultrafast and broadband perovskite photodetectors for large-dynamic-range imaging

    A solution-processed broadband photodetector based on organic-inorganic hybrid perovskite and organic bulk heterojunction has been demonstrated, achieving broadband response spectra up to 1000 nm with a high EQE in the NIR region, an ultrafast response speed of 5.6 ns and a wide linear dynamic range of 191 dB. Encouragingly, due to the high-dynamic-range imaging capacity, high-quality visible-NIR actual imaging is obtained, enabling the accelerated translation of solution-processed photodetector applications from the laboratory to the imaging market …read more
