Definitions

  • Transparent optical panel a solar module, and method of manufacturing the transparent optical panel
  • the invention relates to transparent optical panels for solar modules.
  • Published patent application US2011/0063729 discloses an optical system that allows an image to be displayed on the surface of a solar panel and in such a manner that the image does not form an obstacle to direct solar rays.
  • the system includes a solar panel, a lenticular surface formed from linear lenses, and a transparent film on which straight bands of an image alternate with transparent straight bands (the bands being parallel to the longitudinal axis of the lenses) are printed. At certain viewing angles, an observer can see only the image bands, whereas at other angles of incidence the sun's rays will pass through the transparent straight bands and reach the active surface of the solar panel.
  • the system is particularly suitable for, for example, architectural integration of solar panels, and for disseminating visual information on the surface thereof.
  • the system of the cited patent application is relatively complex. It requires the transparent film and the lenticular surface.
  • the transparent film and lenticular surface have to be positioned accurately with respect to each other in order to focus the sunlight not on the straight bands of the image, and to focus the view of a viewer on the straight bands of the image.
  • solar panels provided with the optical system are relatively expensive.
  • another optimal relative position of the lenticular surface with respect to the straight bands of the image must be found.
  • the panels of the cited patent have to be arranged on a wall of a building, the panels have to be configured individually to obtain the optimal effect. The individual configuration even further increases production costs.
  • a first aspect of the invention provides a transparent optical panel for use as a front panel of a solar module to present an image to a viewer is defined in a first independent claim.
  • a second aspect of the invention provides a solar module comprising the transparent optical panel.
  • a third aspect of the invention provides a method of manufacturing the transparent optical panel.
  • a fourth aspect of the invention provides a method of equipping a building with a solar module.
  • a transparent optical panel in accordance with the first aspect of the invention comprises a first side and a second side.
  • the transparent optical panel is for use as a front panel of a solar module to present an image to a viewer.
  • the image is related to a predefined image.
  • the first side is, in use on a solar module, arranged on or towards an active surface of the solar module.
  • the second side is opposite the first side and receives sunlight.
  • the second side further comprises surface structures which are arranged in a non-uniform pattern to obtain a non-uniform reflection of a part of impinging sunlight towards the viewer.
  • the non- uniformity of the pattern corresponds to intensity and/or color differences in the predefined image.
  • the surface structures are at least one of grooves, ridges, recesses and protrusions, and a width of the grooves or ridges and a diameter of the recesses or protrusions is at least larger than 0.1 millimeter.
  • the surface structures are arranged in the non-uniform pattern, which means that the second side of the transparent optical panel comprises different subareas which have different sub-patterns of surface structures, such as grooves, ridges, recesses and protrusions, in according with sub-images of the image.
  • the sub-pattern may be a uniform pattern.
  • the different sub-patterns may be obtained by creating different densities of grooves, ridges, recesses and protrusions, by arranging the grooves or ridges in different directions, or by creating different shapes with the grooves or ridges. Grooves, ridges, recesses an protrusions may be absent in certain subareas.
  • the surface structures have a typical size (with / diameter) that is larger than 0.1 millimeter and, thus, are the surface structures visible to the viewer and, consequently, the viewer observes that the different subareas comprise different surface structures. Hence, the image is visible to the viewer.
  • the image that is seen by the viewer comprises different light intensities in the direction of the viewer and is, as such, an image with different grey tones. If the predefined image was a color image, the colors are translated towards different amounts of reflection and thus towards different grey tones.
  • Solar modules have in general a transparent panel at its front side, and thus, without introducing additional elements to a solar module and only modifying a surface of the transparent panel, the solar modules provided with the transparent optical panel according to the invention present an image.
  • the cost of the solar module is not much increased, and, thus, a cost effective solution is provided for presenting the image to a person who looks towards the solar module.
  • a solar panel which is provided with the transparent optical panel according to the first aspect of the invention may be better integrated with a building.
  • Today solar panels have another appearance as its surrounding materials.
  • the image may be created such that the panel is better integrated with the surrounding materials of the building, for example, the image may present a pattern that is equal to the pattern of roof tiles, or equal to the pattern of a brick wall.
  • patent application WO2011/016872 discusses a glass substrate which comprises at one of its surfaces a laser etched holographic grating. This means that a specific pattern of grooves or recesses is created in the surface of the glass such that holographic interference between impinging light waves is obtained.
  • the grooves and recesses have a specific size in the micrometer range (in general: a size that is in the range of the wavelengths of light).
  • the effect of the holographic gratings of the cited patent application is that visible light is transmitted through the glass and that light in the infrared spectral range is reflected to prevent heating up of the solar panel by the infrared light.
  • the whole surface of the glass needs to be patterned with the holographic grating.
  • the viewer does not see a specific image on the solar module which is provided with the glass, because visible light is well transmitted through the glass.
  • the surface structures have a specific size that is larger than 0.1 mm, which means that the grooves, ridges, protrusions and recesses are visible to the human naked eye because they reflect at portions of their surface visible light.
  • these surface structures of the invention do not create specific interference patterns which result in the increased reflection of infrared light and the improved incoupling of visible light.
  • the transparent panel which is used at the front side of a solar module, reflects a small portion of the impinging sunlight.
  • the reflected portion is only reflected into one direction.
  • the grooves, ridges, recesses and protrusions have surfaces which have a different angle with respect to the plane of the transparent panel, and as such a small portion of the sunlight is reflected by the transparent optical panel of the invention in many directions. Thus, the viewer will also receive some reflected sunlight.
  • the amount of reflected sunlight by the transparent optical panel of the invention is not larger than the amount of reflected sunlight if no grooves, ridges, recesses or protrusions are provided at the second surface. In such specific configurations, the presenting of the image is not at the cost of efficiency loss.
  • the surface structures such as the grooves, ridges, recesses and/or protrusions, may also act as light incouple structures, which means that the surface structures assist the incoupling of light into the transparent optical panel and, thus, the transfer of sunlight towards the solar module.
  • the surfaces of the grooves, ridges, recesses and protrusions are smooth.
  • Smooth means that, if a function is provided which describes the surface of the groove, ridge, recess or protrusion in a specific cross-section of the groove, ridge, recess or protrusion, the function is at least a partially smooth function.
  • the partially smooth function is a function that is at least continuous and has at least a first order derivative that is continuous. Further, the partially smooth function may have higher order derivatives that are continuous. If the surfaces of the grooves, ridges, recesses and protrusions are smooth, the surfaces do not have abrupt changes of the (local) orientation of surface.
  • Such abrupt changes of the orientation of the surfaces of grooves, ridges, recesses and protrusions may lead to unwanted scattering.
  • the unwanted scattering can reduce the efficiency of the solar module and can reduce the visibility of the image.
  • undesired scattering of impinging sunlight is prevented by the smooth grooves, ridges, recesses and protrusions.
  • the surfaces of the grooves, ridges, recesses and protrusions are transparent.
  • Transparent surfaces are clear surfaces through which light is transmitted without being scattered.
  • the surfaces are not translucent - in other words, the passing of light is not done in a diffuse manner. If the surfaces would be diffuse, the light emission direction of the sunlight would be changed in a plurality of direction, which decreases the efficiency of the solar module. Consequently, the grooves, ridges, recesses and protrusions assist in the incoupling of light such that a relatively large amount of light is transmitted to the solar module.
  • the first side comprises light outcoupling structures for improving the outcoupling of light towards the solar module. If light is incoupled into the transparent optical panel, the light has to be transmitted towards the active surface of the solar module which is arranged, seen from the interior of the transparent optical panel, behind the first side. If the first surface comprises light outcoupling structures, the light is optimally transferred through the transparent optical panel and the amount of light that is captured within the transparent optical panel is relatively small.
  • the non-uniform pattern of surface structures is further configured to assist the incoupling of sun light into the transparent optical panel.
  • the surface structures assist in the incoupling of sunlight, which means that, compared to a situation without surface structures, less light is reflected by the transparent optical panel, and more light is incoupled into the transparent optical panel. If more light is incoupled, more light may be transmitted towards a thermal solar collector or photovoltaic cells in front of which the transparent optical panel is used.
  • the transparent optical panel is manufactured of a material which comprises glass.
  • Glass is a material which is relatively strong and has advantageous light transmission characteristics.
  • the transparent optical panel which comprises glass does not influence the efficiency of the solar module in a negative way. Further, glass ages slowly.
  • the shapes of the grooves, ridges, recesses and/or protrusions will be stable for a long period and the image will remain visible along the lifetime of the solar module.
  • the second side of the optical transparent panel comprises a coating for assisting the incoupling of light into the interior of the optical transparent panel.
  • the surface structures and/or areas of the second side in between the surface structures are coved by the coating.
  • Coatings for providing the effect of increased incoupling of light are known by the skilled person.
  • An example is an anti-reflection coating.
  • the second side comprises a coating for reflecting colored light at large light reflection angles.
  • Large light reflection angles are, in general, larger than 60 degrees with respect to a normal to the second side.
  • Colored light is light that has another color than direct sunlight, thus, colored light is not white light.
  • viewers look towards a solar module at relatively large viewing angles, and thus, the viewer sees in addition to the image a colored surface. This may be advantageous in applications wherein the solar module needs to have the color of the surrounding area of the building to which it is provided..
  • a solar module for receiving solar radiation and for converting the received solar radiation into another form of energy.
  • the solar module comprises the transparent optical panel according to the first aspect of the invention and the transparent optical panel is arranged at a side of the solar module for facing the sun.
  • the solar module according to the second aspect of the invention provides the same benefits as the transparent optical panel according to the first aspect of the invention and has similar embodiments with similar effects as the corresponding embodiments of the transparent optical panel.
  • the solar module may be used on a roof or a wall and the image that is visible to the viewer may be, for example, an images that matches the appearance of other parts of the roof or which matches the structure of the wall. Thus, the solar module may be less visible, which is often experienced by people as an advantage.
  • the image is a logo of a company and, thus, the solar module has a double function of providing energy and advertising the company logo to the viewer.
  • the solar module is a thermal solar collector.
  • the solar module is a photovoltaic solar module.
  • the photovoltaic cells are laminated to the first side of the transparent optical panel.
  • the transparent optical panel forms together with a second panel and a sealing means an air and humidity tight sealing for the photovoltaic cells and the photovoltaic cells are provided in between the transparent optical panel and the second panel.
  • the second panel comprises glass.
  • the solar module further comprises fastening means for fastening the solar module to a roof or a wall.
  • a first method of manufacturing a transparent optical panel for use in a solar module and for presenting an image to a viewer comprises the steps of i) providing a transparent panel comprising a first side for being arranged on or towards an active surface of the solar module and comprising a second side being opposite to the first side for receiving sunlight, ii) providing a coating according to a non-uniform pattern on the second side, wherein the non-uniform pattern is based on the image and the non-uniformity of the pattern is based on intensity and/or color differences in the image, iii) etching away material of the transparent panel at the second side at areas without the coating to obtain at least one of grooves, ridges, recesses and protrusions, wherein a width of the grooves or ridges and a diameter of the recesses or protrusions is at least larger than 0.1 millimeter, iv) removing the coating from the second side.
  • the step of etching away material may be performed with chemicals.
  • the use of an etching technique allows the creation of customized transparent optical panels which present a customized image to the viewer because the pattern in which the coating is provided may be customized.
  • etching is a relatively cheap technology to create grooves, ridges, protrusions and/or recesses in the surface of the second side of the transparent panel. Ridges and protrusions may be obtained by etching away material around the location where ridges and protrusions have to be manufactured. Grooves and recesses may be obtained by etching away material at the location where grooves and recesses have to be manufactured. Another used term for the 'coating' is 'resist'.
  • the step of providing the coating comprises screen-printing the coating.
  • Screen-printing is a technique with which a large number of transparent plates may be printed with the non-uniform patterned coating in a cost effective manner. This is, for example, advantageous if a series of transparent optical panels have to be manufactured in which all the transparent optical panels present the same image to the viewer.
  • the step of proving the coating comprises printing the coating.
  • Printing is, for example, done with an inkjet technology, wherein the ink is substituted by the coating.
  • each manufactured transparent optical panel can be individualized such that a custom selected image is presented to viewers.
  • a company logo must be presented by the solar modules provided with the transparent optical panels, each transparent optical panel has to be provided with an individualized image.
