Definitions
- thermodynamic limit is theoretically a factor of 46200-fold concentration. This limit is reached when the solar cell receives radiation from the complete half space.
- Techniques for concentrating light are well known and concentrations up to a factor of about 1000 can be used. In order to achieve very high concentrations, in addition
- Photovoltaic concentrator system is advantageously so positioned between the at least one concentrating optic and the at least one solar cell that it is directly on the solar cell, on an applied to the solar cell intermediate layer, in particular a silicone layer, spaced from the solar cell through an air gap or disposed directly on the Primärkonzentratorsystem ,
- the air gap is preferably significantly wider than the wavelength of the considered light.
- the air gap may be at least a few ⁇ m, preferably at least 1 ⁇ m, preferably at least 5 ⁇ m, wide.
- the angle-selective filter is spaced from the solar cell by an air gap, existing photovoltaic systems with at least one concentrating optics and at least one solar cell can be reconstructed so that independently developed angle-selective systems or filters are integrated between the solar cell and the concentrating optics.
- the width of the air gap is preferably a few microns. It seems advantageous to use the angle-selective Ven filter near the focal point of the lens and in front of the solar cell to position, as this the surface and thus the price of the angle-selective element can be kept as low as possible.
- the location of the filter can be chosen arbitrarily between solar cell and concentrating optics. In particular, when taking into account the chromatic aberration, however, it is preferable to choose slightly larger or smaller distances than the focal length of the focusing optics.
- the tracking system should therefore be as accurate as possible so that the filter can limit this range as far as possible.
- direct sunlight at an angle in the range of 0 ° to 1 °, in particular from 0 ° to 0.5 °, incident to the vertical in the Photovoltaikkonzentratorsystem, in particular impinges on the angle-selective filter.
- Concentrator system are preferably 2D or 3D photonic crystals, in particular normal and / or inverted opals, or interference layer filters, in particular rugate and / or edge filters, can be used.
