Embodiment Construction
[0019] figure 1 A concentrating system 1 comprising a first optical element 3 and a second optical element 5 is shown. The concentrator system 1 forms a concentrator solar module 9 together with photovoltaic elements (solar cells 7 ).
[0020] In the following, the light concentrating system 1 and the concentrator solar module 9 are described in the order of the path of light illuminating the light concentrating system 1 along the optical axis O. The incident light 11 illuminates the first optical element 3 . The incident light 11 is usually sunlight and can therefore be seen as a bundle of parallel rays. Preferably, the first optical element 3 is arranged in such a way that the incident light 11 is illuminated at normal incidence. this is in figure 1 Indicated by a right angle. To maintain normal incidence, the concentrator solar assembly 9 may be provided with an automatic tracking system (not shown) that follows the relative motion of the sun.
[0021] The first optic...

Concentrating systems and concentrator solar modules for solar modules. The invention relates to a concentrating system (1) for a solar module, in particular for a concentrator solar module (9), for concentrating incident light into solar energy such as a solar module On the target area of the cell (7), the system includes a first optical element (3) for collecting incident light and forming a light cone (13) towards the target area (17) and a second optical element (3) adjacent to the target area (17). Two optical elements (5). In order to provide a concentrating system (1) and a solar module for a solar module allowing efficient and easy-to-manufacture light transmission and concentration, according to the invention it is intended that the first optical element (3) be a multifocal element and that the second The optical element (5) is adapted to reflect light to at least one area (34) of the target area (17) outside the center (23) of the target area (17).
Description
technical field [0001] The invention relates to concentrator systems and concentrator solar modules. Background technique [0002] Concentrating systems and concentrator solar modules are known in the prior art. They can be used to focus sunlight onto a target area. In the target area, high-efficiency photovoltaic elements such as solar cells or solar thermal absorber elements can be placed. In the light concentrating systems known in the prior art, optical systems are used which are expensive, laborious to manufacture, lose efficiency due to strong inhomogeneous illumination, or lose most of the light due to absorption and / or reflection, and Therefore has lower efficiency. Contents of the invention [0003] It is therefore an object of the present invention to provide a concentrator system and a concentrator solar module that is easy to manufacture and provides a high concentration yield as well as homogenization of the illuminance on the target, namely photovoltaic el...
