摘要: The present invention relates to an organic-inorganic hybrid short-wave infrared photoelectric detector. A photosensitive layer of the short-wave infrared photoelectric detector comprises a lead sulfide quantum dot thin film with an energy gap≤1.24 eV, and a donor-acceptor-blended organic semiconductor structure. Compared with a photoelectric detector with pure lead sulfide quantum dots, the organic-inorganic hybrid photosensitive layer improves the external quantum efficiency of the photoelectric detector in a short-wave infrared region, reduces a dark current density, and improves a response speed, such that the specific detectivity of the photoelectric detector is improved by an order of magnitude. It is worth mentioning that the photoelectric detector can show excellent comprehensive performance under a zero-bias voltage or a relatively low reverse bias voltage. The present invention further relates to an array formed by the photoelectric detector, and a preparation method related thereto.

摘要: A photoelectric conversion device includes a substrate and a wiring layer disposed on the substrate. The wiring layer includes a wiring structure and a wiring insulating layer that surrounds the wiring structure. A reflective layer is disposed on the wiring layer. The reflective layer is electrically connected to the wiring structure. A semi-permeable metal layer is spaced apart from the reflective layer in a thickness direction of the substrate. The semi-permeable metal layer faces the reflective layer to form a microcavity between the reflective layer and the semi-permeable metal layer. A stacked structure is between the reflective layer and the semi-permeable metal layer in the thickness direction of the substrate. The stacked structure includes a photoelectric conversion layer, a transparent electrode layer, and an insulating optical spacer.
