Description

PARABOLIC CONCENTRATING PHOTOVOLTAIC CONVERTER Technology
Invention deals with the parabolic concentrating photovoltaic converter, where the problem of solar radiation concentration on the high concentration photovoltaic cell is solved. The solution belongs to the area of usage of the photovoltaic effect for the combined conversion of the highly concentrated solar radiation into the electric power and low-potential heat.
Actual state of technology
Current perspective technology of energetic usage of the solar energy is CPV (Concentrating Photo Voltaics) or HCPV (High Concentration Photo Voltaics). Different types of reflecting or lens concentrators are used for concentration of the direct solar radiation on the active surface of concentrating photovoltaic cells. The most widely known among them are flat mirrors, parabolic channels or paraboloidal mirrors or Fresnel Lenses. As compared to the mirror concentrators, concentrators with Fresnel Lenses have one disadvantage - lower optical pressure. Common disadvantage of mirror and Fresnel concentrators is gradual worsening of the optical characteristics by degradation of the used optical materials due to the atmospheric impacts and UV radiation.
Subject of the technical solution
The above stated disadvantages are to the great extent eliminated by the parabolic concentration photovoltaic converter formed by parabolic concentrating mirrors and concentrating photovoltaic cells placed in the areas of the concentrators' focusing. The main idea of this concentrator is that the solar modules are formed by rectangular offset parabolic mirrors that are individually or dually reverse arranged into the rows of mirrors, and by concentrating photovoltaic cells placed in the areas of the concentrators' focusing away from the input solar radiation aperture, with the offset parabolic mirrors with concentrating photovoltaic cells being protected against the external environment by the protective glass. Thermal connection of the concentrating photovoltaic cell with the cooling side wall of the solar module is formed mainly by the metal plate, electrically nonconductive foil and cooling pattern with cooling surfaces universally adapted for heat removal to the cooling side wall of the solar module as well as to the central fluid cooling channel, with concentrating photovoltaic cell and ceramic insulators being mechanically, electrically and thermally connected to the metal plate, mainly by means of brazing.
Advantage of the parabolic concentrating photovoltaic converter solution according to the utility model is its enhanced mechano-climatic properties with high optical efficiency (above 90%) and competitiveness of the economic costs.
Overview of the images on the drawings
The attached drawings contain simplified examples of the parabolic concentrating photovoltaic converter and its parts construction, where the pictures Ia and Ib show in section two examples of solar modules with passive cooling of the concentrating photovoltaic cell, picture Ia shows an independent solar module, picture Ib - a dual optical reverse module. Picture 2 shows in section an example of a dual solar module with an active cooling of the concentrating photovoltaic cell; pic.3 contains a front view of dual optical solar modules arranged in lines with active cooling using; pic.4 - a side view of the photovoltaic cell installation method on the cooling pattern by means of metal plate and electrically non- conductive foil; pic.5 - a front view of the photovoltaic cell installation on the metal plate equipped with contact ceramic insulators.
Realization examples
Solar module of the parabolic concentrating photovoltaic converter is formed by the offset parabolic mirror 1 of the rectangular shape with square or rectangular aperture and concentrating photovoltaic cell 2 placed in the focusing area of the concentrator away from the input solar radiation aperture, by means of the cooling pattern 3, which is in the first two examples with the usage of the photovoltaic cell 2 passive cooling, is thermally connected to cooling side wall 4 of the solar module, pic. Ia, pic. Ib, and in the third example with the usage of the concentrating photovoltaic cell 2 active cooling is thermally connected to the central liquid cooling channel 5, pic.2. In all examples the offset parabolic mirrors 1 and concentrating photovoltaic cells 2 are protected against the external environment by means of the protective solar glass 6. Solar modules can be individually or dually optically reverse arranged into rows mirror 7, for example into double-rows pattern with the use of the central liquid cooling channel 5, pic.3. The concentrating photovoltaic cell 2 is directly mechanically, electrically and thermally connected to the metal plate 8, which is electrically isolated from the cooling pattern 3 and thermally connected by means of the electrically nonconductive foil 9, pic.4. The metal plate 8 to which the concentrating photovoltaic cell 2 is connected mainly by means of blazing, can be completed with contact ceramic insulators 10 and fastening holes 11 for electrically insulating bushings 12 and fastening screws 13, pic.5.
Industrial use
According to the utility model the parabolic concentrating photovoltaic converter can be used for the economically effective solar production of the electric power and low potential heat in the centralized and decentralized power engineering.
