  • Publication number: 20240304743
    Abstract: This disclosure relates to a dielectric layer response-based field effect transistor photodetector, comprising a gate, a photoelectric response composite dielectric layer, a carrier transport layer, a source, and a drain. The composite dielectric layer is formed by compounding a photoelectric response dielectric and a charge blocking insulating dielectric; the carrier transport layer is used for transporting electrons or holes, the photoelectric response dielectric is used for absorbing light under illumination to generate electrons, holes or excitons, and the charge blocking insulating dielectric is used for limiting passage of the electrons, holes or excitons.

  • Patent number: 10199528
    Abstract: A mesoscopic solar cell, including: a conductive substrate, a hole blocking layer, a mesoporous nanocrystalline layer, an insulation separating layer, and a hole collecting layer, and perovskite light absorption materials. The hole blocking layer, the mesoporous nanocrystalline layer, the insulation separating layer, and the hole collecting layer are sequentially laminated on the conductive substrate. The perovskite semiconductor materials are filled in the mesoporous nanocrystalline layer, the insulation separating layer, and the hole collecting layer, which enables the mesoporous nanocrystalline layer to be an active light absorption layer operating as a photoanode, and enables the insulation separating layer to be a hole transporting layer.
