Definitions

  • Concentration is associated with disadvantages because the method works only with direct radiation and the reflectors give away a great deal of area with nonconcentrable, diffused light.
  • Their size depends on the location of the desired performance and the concentration. On a roof surface one will use smaller (narrower) modules and concentrators for visual and static reasons than for outdoor installation. Since the solar cells or the solar modules have the largest share of the total costs, it makes economic sense to keep these components as small as possible.
  • SUBSTITUTE SHEET Reflectors are essential for reaching high temperatures and are therefore also in regions . used with many hours of sunshine and high direct radiation intensity for the deflection and / or concentration of light. In areas that are not spoiled by the sun, z. For example, Central and Northern Europe, both radiation components, direct and diffuse, about the same size over the year.
  • Diffused light has the disadvantage that it can not be concentrated by refractive or reflective means.
  • Solar cells are almost equally sensitive to both types of radiation. If solar modules are combined with concentrators, this means that with direct solar radiation and a concentration factor of 10.90% of the light is diverted through the concentrators and 10% is directly converted by the solar cell. The area ratio between concentrators and solar cell is accordingly 90/10. If there is no direct radiation but only diffused light, only the 10% area fraction of the solar cells can be used, the 90% share of the concentrators is lost. This applies to thermal and photovoltaic solar cells.
  • the object of the invention is to provide a method in which electricity and heat can be produced by a solar cell array and the land use and efficiency is greatly improved. According to the invention the object is solved by the features of the claims and the dependent claims.
  • the concentrators By coating the concentrators with cheap solar cells, for example amorphous silicon, preferably in the form of thin-film cells which may also be flexible, their reflection properties are only moderately affected and they are also able to direct radiation directing concentric on the preferably centrally arranged, thermal solar cell , However, they can themselves convert part of the solar radiation, preferably the nonconcentrable diffuse light, into electricity. This means that always 100% of the total area available for light conversion and only change the proportions of the various transducers depending on the type of radiation.

This means that always 100% of the total area available for light conversion and only change the proportions of the various transducers depending on the type of radiation.
  • the shape of the reflector is chosen so that direct radiation components are deflected by total reflection at the reflector side close to the sun.
  • mirror losses are minimized and through the efficient Conversion of light in the thermal solar cell, higher temperatures and improved efficiency.
  • the main body of the reflector is made of hard or / and dimensionally stable material, in particular of organic or inorganic materials such as glass, ceramic, metal and plastic or mixtures thereof.
  • the main body can be directly equipped with thin photovoltaically active layers, but also as a carrier of separately produced solar cells, preferably in the form of films or tiles, etc., can be used.
  • These carriers are adhered to the body, laid, stretched, etc., that they at least largely conform to its shape.
  • a carrier of transparent material in which the solar cells are arranged on the solar side.
  • the substrate is glass
  • with total reflection well over 90% of the direct radiation can be concentrated on the central solar cell, and at the same time the remaining direct radiation and the diffused radiation can be converted by the thin film solar cells.
  • Solar tracking around at least one axis improves the yield whenever direct radiation is present. In order to set up the solar cell array on roofs of residential buildings, they must not be very high.

  • Concentrators Fig. 3 to Fig. 5, the exemplary position nacher Siliconter concentrators during the day.
  • the transparent cover 6, which preferably consists of mineral or synthetic glass and rests on the side walls of the tub 5, can fulfill several tasks by protecting the dirt-sensitive, light-guiding surfaces from adverse weather conditions, has a heat-insulating effect and by a suitable, preferably anti-reflection surface structuring the efficiency improved.
  • the material of the carrier 1 is preferably selected so that the wavelengths of the penetrating solar radiation enable a low-loss conversion into electricity. This can be achieved for example by fluorescent properties.
  • FIGS. 3 to 5 show, by way of indication, different orientations of the concentrators which are tracked to the sun. The tracking can be one or two axes.
  • the distance between the tub bottom 5 and the cover 6 is preferably so large that the concentrators can also be pivoted beyond the vertical.
