摘要: A photodetector comprises a graphene layer formed on a substrate, and a photoactive structure formed on the graphene layer. The photoactive structure comprises quantum dots and a ferroelectric polymer layer, and configured to generate carrier holes when illuminated. The ferroelectric polymer layer has an internal electric field that extends into the graphene layer to facilitate transport of photoinduced carrier holes from the photoactive structure into the graphene layer, thereby improving photoresponse of the photodetector.

摘要: A wireless optical power transmission system comprising a transmitter and receiver, the transmitter comprising a laser emitting a beam, a scanning mirror for steering the beam towards said receiver and a control unit receiving signals from a detection unit on the receiver and controlling the beam power and the scanning mirror. The receiver has a photovoltaic cell having a bandgap energy of 0.75-1.2 e V, with a plurality of conductors on a beam receiving surface. A cover layer of material blocking illumination of wavelengths outside that of the laser, is disposed on the photovoltaic cell. The cover layer may have anti-reflective coatings on its top and bottom surfaces. The detection unit thus generates a signal representing the power of the laser beam impinging upon the receiver, independent of illuminations other than that of said laser beam. The control unit thus can maintain the laser power impinging on the receiver.
