- the mirror body may be colored, in particular incorporated in the design of a facade or, for example, steep, pitched roof.
- the mirror body may be substantially semipermeable or substantially semitransparent or substantially semipermeable, so that on the one hand the sun is reflected onto the photovoltaic absorber means and on the other hand the mirror body from the back translucent.
- a semipermeable or semitransparent or semipermeable embodiment of the mirror body a use is made possible, for example, office buildings; In general, the façade design is given a high degree of flexibility thanks to this optional feature.
- lower half of the mirror (or left or right mirror half in facades) is substantially opaque or substantially mirrored and
- the upper half in relation to the position of the sun and / or with regard to the attachment to the façade (or right or left half of the façade of facades) is essentially translucent or substantially transparent
- the façade design achieves a high degree of flexibility.
- the Roof slope modules have at least one connected to the thermally conductive metallic side panels angled cooling surface in order to transfer the heat occurring on the roof surface can. Since the side parts of the mirror body used for mounting can thus be thermally conductive and connected to the absorber carrier or photovoltaic carrier, they serve in an advantageous manner in addition to the heat dissipation from the concentrator.
- optically active which contribute significantly to the concentration of light
- the concentrator as a light reflector, in particular for L [ight] E [mitting] D [iode (s)], for facade lighting and / or for advertising and / or
- the absorber carrier as a support or mounting surface for LED.
- This property has the further effect that the optically inactive surfaces can be used for design purposes or for artistic purposes to make the photovoltaic surfaces visually attractive. This can be done by color and / or structural changes of the mirror and / or the entire concentrator or by attaching bulbs, such as lights, in particular of L [ight] E [mitting] D [iodes], inside and / or outside the concentrator.
- the LED can also be arranged in the concentrator so that the concentric in cross-section concentrator can be used both as a light reflector and as facade lighting and as a billboard. In this case, the LEDs can also be mounted on the surfaces of the absorber carrier, which are not covered with absorber material.
- the illumination of individual concentrators with activated LED can be used for the display of images, logos and / or copywriting.
- the light effect concentrators may be arranged to exhibit "pixel” effects when viewed from a distance, allowing the "pixel” representation of logos; This is particularly important for pitched roofs and facades of importance because such areas can also be used for advertising purposes, lighting effects at night or the like.
- FIG. 1 is a schematic cross-sectional view of an embodiment of a device according to the present invention, which operates according to the method according to the present invention, in the case of a roof pitch of 45 degrees (see Fig. 1 left) or in the case of a roof pitch of sixty degrees ( see Fig. 1 right);
- FIG. 4B shows a schematic perspective illustration of an exemplary embodiment of a dome of the mirror body with a second exemplary embodiment of a presetting means or a holder, namely in the form of holes, for mounting the photovoltaic absorber means on the side parts of the mirror body;
- 4C is a schematic perspective view of an embodiment of a dome of the mirror body with a third embodiment of a Voreinwolfsmittels or a holder, namely in the form of slots or grooves, for mounting and for continuous and / or continuous tracking of the photovoltaic absorber means to the
- Fig. 7 in a schematic cross-sectional view of an embodiment of a dome of the mirror body, wherein the lower part of the dome with respect to the incident light opaque or mirrored and the upper part of the dome with respect to the incident light is translucent or transparent.
- FIG. 1 shows how the photovoltaic absorber means 20, the less favorable position by fifteen degrees at a roof pitch of sixty degrees (see right half of Fig. 1) against a roof pitch of 45 degrees (see the left half of Fig. 1) by the position of the photovoltaic absorber means 20 within the concentrating mirror body 10 can compensate. Because the Kaustikkurve K mit mit the angle of the incident light L, the photovoltaic absorber 20 remains with a roof pitch correcting angle correction in an optimal position to the incident light L. In Fig. 2 are the two extreme cases
- the photovoltaic absorber 20 is arranged in the calotte 10, that the photovoltaic absorber 20 touches the Kaustikkurve K and that straight line, which is given in a symmetrical arrangement with incidence of light from above as perpendicular bisector, now parallel (relative to a specific year-dependent position of the sun) for incident light L stands.
- the reason for the operation with high energy yield even in these two extreme cases of FIG. 2 lies in the symmetry of a spherical cross-section mirror 10 and in the fact that in a spherical cross-section mirror 10 not the whole semicircular calotte contributes to the light concentration, but only a section.
- FIG. 3 shows an exemplary embodiment (with exemplary dimensions) in which such a section is ⁇ 45 degrees to the mid-perpendicular of the mirror-shaped mirror body 10 and thus the entire optically concentrating active part ninety degrees relative to the position of the absorber 20 within the Cross-section of spherical mirror 10, is. This optically active region then travels at the angle of incidence of the light L.
- an optically active aperture of about 135 millimeters results in a radius R of about one hundred millimeters, and an optically active aperture of about seventy millimeters for perpendicularly incident light L. at a radius R of about fifty millimeters.
- reference numeral 30 denotes a preset means in the form of a mount for mounting (see Fig. 4A, Fig. 4B) or for continuous and stepless tracking of the photovoltaic absorber 20, for example at the Spiegelkalotte.
- the absorber 20 is fixedly mounted during fabrication or assembly on the roof or on the facade.
- Mounting holes 30 for mounting the photovoltaic absorber means 20 to the dome of the transversal spherical mirror 10 are used for this purpose (see Fig. 4A: Fig.

- FIG. 4C mounting slots or mounting grooves 30 for mounting the photovoltaic absorber means 20 on the side parts of the cross-sectional mirror 10
- FIG. 4C the possibility of a continuous and continuous tracking of the photovoltaic absorber means 20 is given (in the embodiment according to FIG. 4A, FIG. 4B, the tracking in favor of the default setting is omitted).
- Fig. 5 shows a comparative composition with respect
- This comparative arrangement according to FIG. 5 illustrates how, in the production of the photovoltaic concentrator 100 according to the present invention, the adjustment of the photovoltaic absorber 20 can be made within the spherical concentric concentrator 100, depending on the field of application (sloping roof, flat roof , Facade) an optimal energy yield is achieved.
- This property can be achieved, in particular, by means of a concentric device 100 having a spherical cross-section, and consequently with a Kaustik curve K that migrates with the incidence of light.
- the spherical cross-section calotte mirror semipermeable or semitransparent or semipermeable when mounted on facades, it may be advantageous if the spherical cross-section calotte mirror semipermeable or semitransparent or semipermeable, in particular
