  • Publication number: 20230213702
    Abstract: An apparatus is described for converting light of a light source into electrical energy. The apparatus includes a layered body having flat elements, a photovoltaic cell, a light conducting element, a light-switching element , and a photovoltaic cell arranged on a boundary surface of the layered body. The light-switching element (16) can be set to either transmit or block light, In the case of blocking, the light-switching element couples light into the photovoltaic cell t to convert received light into electric energy.

  • Publication number: 20220413288
    Abstract: A motor vehicle includes a display system having an image source positioned in a dashboard of the motor vehicle for emitting light beams. A reflection region extends in parallel to a lateral edge of a pane layer of a windshield of the motor vehicle. The reflection region is configured to reflect the light beams to generate a virtual image and the image source includes a one-dimensional switchable strip display. A controller of the motor vehicle is configured to provide, by using the one-dimensional switchable strip display corresponding to the virtual image, at least one of a dynamic running light and a static light strip.

  • Publication number: 20210193855
    Abstract: The present disclosure relates to a photovoltaically active laminate that includes a cover film, a photovoltaic active solar cell film, and a fiber composite support layer. The cover film defines a top surface of the laminate and is transparent to incident light radiation. The photovoltaic active solar cell film includes a support film and a coating of a photovoltaically active material applied to the support film. The cover film has a thickness in a range up to 1 mm. The solar cell film has a thickness in a range between 0.06 mm and 2 mm. The support layer has a thickness in a range between 0.8 mm and 3 mm.

  • Patent number: 8557390
    Abstract: The present invention relates to a glass product, comprising a glass substrate with a transparent and conductive indium tin oxide layer having a covering layer, which forms a redox barrier for the indium tin oxide layer, wherein the indium tin oxide layer is obtained by pulsed, highly ionizing high-power magnetron sputtering (HPPMS) in which—the pulses of the magnetron have a peak power density greater than 1.5 kW/cm2,—the pulses of the magnetron have a time duration that is ?200 ?s, and—the mean current flow density rise upon ignition of the plasma within a time interval that is ?0.025 ms is at least 106 ?(ms cm2), and the indium tin oxide layer has a crystalline structure, in such a way that the (222)-reflection of an X-ray diffraction spectrum after the production of the indium tin oxide layer is shifted relative to the powder spectrum of indium tin oxide by a maximum of 1 degree, preferably by 0.3 degrees to 0.

  • Patent number: 7245205
    Abstract: The invention concerns a vehicle with a window pane, especially a front window, a rear window, a side window or a roof window, for covering of the internal space of the vehicle. The transparency of the window pane is adjustable, and the vehicle includes a control for automatic adjustment of the transparency of the window pane as a function of an operating state of the vehicle.
