Description

, 100268

This invention relates to a collecting solar cell comprising collecting elements capable of absorbing sunlight / heat on both surfaces.

Solar cells of the type described above are disclosed, for example, in Swiss Patent Publication No. 595599 and American Patent Publication No. 4047517.

10 These publications disclose elements which are basic in the form of plates and consist of two planes with a liquid or piping between them. Both surfaces of the elements are absorbent.

With the help of the above-mentioned solutions, heat collection has been made more efficient. However, solutions 15 are only halfway there, as a significant part of the thermal energy still escapes out of the reach of collectors.

It is an object of the present invention to further enhance heat collection. This is accomplished as set forth in the appended claims.

The invention will now be described in more detail with reference to the accompanying drawings, in which: Figure 1 shows a sectional view of an embodiment of the invention;

Fig. 2 shows an exemplary structure of one unit of a collector in a cross-sectional view, and Fig. 3 shows the structure according to Fig. 1 now, however, in an axonometric view.

As can be clearly seen from the figures, the collector 1 according to the invention is constructed of collector waste elements 2, 3, 4, the numbers of which show the elements 2 in different layers. It should be noted here that in addition to the full circle pattern shown in the figures, the elements can also be placed on a partial circular arc or an arc that is not directly a circle.

It is essential that there is a certain space between the elements in each layer, e.g. 2.2, and that the elements of the next layer, e.g. 3, 3, are located substantially at these spaces. There is a desired number of element layers, but increasing the number beyond 3-4, for example, hardly brings about a substantial improvement in results.

Both surfaces of the elements 2, 3,4 are well absorbed by sunlight and heat and of a color suitable for the purpose. The heat collected by the elements is transferred to utilization in any known manner. The conventional way is to make the elements liquid-filled and to circulate the liquid outside the element for heat transfer. Another way is to bring the piping into the liquid, where heat is collected in the filing medium. A third method is shown in Figure 2, in which the element is filled with or made of a solid substance 5 and includes channels 6 filled with a heat collecting medium.

Fig. 1 shows by way of example with arrow 7 how sunlight can pass through refraction and reflection in a collector according to the invention, so that even the last energy strip is recovered therefrom.

The collector according to the invention is placed in a suitable place and can also be placed vertically well in order to save space.

The elements 2, 3, 4 of the collector according to the invention can have the desired shape. In cross section, they can be, for example, squares, rectangles or arcs.
