Superior performance and ultrafast response from CH3NH3PbI3 based UV–visible broadband photodetector using 1D carrier transport layers

Ag-Nanoparticle-Coupled UV-Responsive Gelatin Nanofiber Photodetectors

“…Nevertheless, the electrical characteristics of devices with thin-film structures generally exhibit higher leakage currents; therefore, the photosensitivity of photodetectors is restricted with the surface-to-volume ratio for UV exposure. Nanomaterials, particularly one-dimensional (1D) nanostructures, can extend the lifetime of photogenerated carriers due to the surface-to-volume ratio. , Furthermore, much attention has been paid to the fabrication and development of charge carriers because that effective area shortens the transport time and thus increases the response speed. , …”

“…5,6 Furthermore, much attention has been paid to the fabrication and development of charge carriers because that effective area shortens the transport time and thus increases the response speed. 7,8 In this regard, Reddy et al fabricated p-type 1D NiO nanowires on Si−n substrates using electrospinning techniques to form a heterojunction that provides outstanding rectification, low dark current, and photosensitivity in the UV region. 9,10 Nami-Ana and co-workers synthesized an aspartic acid/polyaniline nanofibers nanocomposite to detect different concentrations of Co sensing, which has enhanced gassensitive properties due to an increase in the surface area of gas adsorption.…”
