Definitions
- the invention relates to a light-transmissive flat body with two transparent cover layers, which enclose between them an active layer that changes their light transmission in an electrical field between two electrode layers, which may be divided into sections, and with a photovoltaic element, preferably connected via a control stage to the electrode layers, the one has photoactive layer between two electrode layers.
- Translucent flat bodies such as those formed by liquid crystal displays or window panes which are controllable in terms of their translucency, have an active layer which changes their translucency in an electric field between two electrode layers which may be divided into sections, via which the electric field required for controlling the active layer is applied at least in sections.
- the essentially layer-parallel liquid crystal molecules form nematic rotating cells, the liquid crystal molecules rotating in the direction of the field when an electrical field is applied and returning from the field-oriented state to the twisted structure after the electrical voltage has been switched off.
- polarization filters on both cover layers of the active layer, the field-oriented state can be sorption can be made visible.
- Electrochromic active layers are based on the interaction of two colorless or only weakly colored, on the one hand oxidizable and on the other hand reducible substances, one of which is reduced under the influence of an electrical voltage and the other is oxidized, at least one of these substances becoming colored. After switching off the voltage, the two original redox substances re-form, with a decolorization or color brightening.
- photovoltaic elements are suitable for the energy supply, especially since the light sensitivity of photovoltaic elements enables simple, independent control of the light transmission of the active layer .
- a disadvantage of the photovoltaic elements used for this is that they must have a sufficiently large receiving area for light radiation in order to ensure the required energy supply. The space required for this increases with decreasing efficiency. This applies in particular to photovoltaic elements whose photoactive layer is not conventionally based on silicon, but on conjugated plastics, in which single and double bonds alternate.
- the invention is therefore based on the object to provide a translucent flat body of the type described above via a photovoltaic element with the energy required for controlling the active layer, with a comparatively low design effort, without providing additional space for the arrangement of the photovoltaic element have to.
- the invention solves this problem in that the photoactive layer of the photovoltaic element consists in a known manner of two translucent molecular components, that one of the two electrode layers of the active layer is also one of the electrode layers of the photovoltaic element and that the two transparent cover layers both Include photovoltaic element as well as the active layer between them.
- the translucent flat body itself can serve as a support for the photovoltaic element, so that the photovoltaic element can extend over the entire area of the translucent flat body. In this way, even with a comparatively low efficiency of the energy conversion, sufficient electrical energy can be made available for controlling the active layer of the translucent flat body.
- the design effort remains low because one of the two electrode layers of the active layer of the translucent flat body is used as an electrode for the photovoltaic element, the photoactive layer of which is thus built up on the one electrode layer of the translucent flat body.
- the photovoltaic element Since in general the energy supply of the flat body which can be controlled with regard to its light transmission is to be ensured independently of the light transmission chosen in each case, it is advisable to arrange the photovoltaic element on the side of the active layer facing a light source.
- the translucent flat body has two transparent cover layers 1, 2 made of glass or plastic, which between them include on the one hand an active layer 3 for controlling the light transmittance and on the other hand a photoactive layer 4 of a photovoltaic element 5.
- the active layer 3 can be constructed in the usual way as an electrochromic layer, which can be exposed to an electrical field between two adjacent electrode layers 6 and 7, via which the light transmittance of the active layer 3 is controlled.
- These electrode layers 6 and 7 preferably consist of an indium tin oxide (ITO), but in contrast to conventional ones, with regard to their Translucent controllable flat bodies, in particular window panes, only one of the two electrode layers 6, 7 is applied to a transparent cover layer 1.
- ITO indium tin oxide
- the electrode layer 6 facing away from the cover layer 1 is namely at the same time an electrode layer for the photovoltaic element 5, the other electrode layer 8 of which is assigned to the cover layer 2.
- the photoactive layer 4 of the photovoltaic element 5, which can be constructed in multiple layers, consists of a conjugated polymer as an electron donor and a fullerene as an electron acceptor. While the hole-collecting electrode layer 6 consists of a transparent, conductive oxide, the electron-collecting electrode layer 8 of the photovoltaic element 5 can consist of aluminum, which is evaporated onto the photoactive layer 4. Because of the small layer thickness, the metallic electrode layer 8 is also translucent.
- the active layer 3 is not built up from electrochromic substances, but is created on the basis of liquid crystals, the mode of operation of the active layer 3 changes, but not its activation via the photovoltaic element 5.
- the cover layers 1 and 2 must, however, have corresponding polarization layers 12 and 13 are provided, as indicated by dash-dotted lines in the drawing, in order to align the liquid To be able to use crystal molecules in the direction of the electric field for shading the translucent flat body.
- the translucent flat body is shown in the form of a window pane in the drawing, the invention is not limited to this embodiment, but can also be used in connection with a liquid crystal display.
- the electrode layer 7 is to be subdivided accordingly and the parts are to be actuated separately from one another in order to obtain a display as a result of the activation of individual liquid crystal cells of the liquid crystal cells of the active layer 3 arranged in a matrix pattern.
- an active layer 3 for controlling the light transmittance with a photovoltaic element 5 for supplying energy for the control of the active layer 3 in a common, translucent flat body
- simple constructional relationships are created which allow the common use of an electrode layer 6 between the active layer 3 and the photoactive layer 4 and enable the transparent cover layers 1 and 2 for the two layers 3 and 4.
- the two layers 3 and 4 can be sealed together, because only the edge-side gap between the cover layers 1 and 2 is to be sealed by means of a seal 14.
- the mutual spacing of the cover layers 1 and 2 can be ensured by spacers 15, which preferably carry the electrical connections 9 and 10.
