Solar cells1 by using both the front and the back of the cell for the conversion of light into electricity The invention relates to a method for increasing the power output of solar cells' by using both the front and the back of the cell for converting light into electricity by coating the Substrate of heterogeneous semiconductor cells and / or bilateral diffusion of Boundary layers on the basic cell of homogeneous semiconductors, according to known application processes and / or optionally your own arrangement of the coating and / or your own boundary layer configuration and / or own contact configuration, to promote the mutual conversion of Light in electricity with a favorable radiation arrangement and economical lightweight construction of solar cell generators, consisting of solar cells with contacts, power lines and reverse current blocking diodes, in rope ladder fashion by wire and / or other suitable ones Materials Reinforced, clear plastic sheath straps and / or plates and / or other suitable material, optionally in range, hinged and / or Rigid frame shapes and / or tension wire constructions built in the better Enabling illumination of the solar cells, excellent but clamped in the upper one Hypotenuse side of a prismatic hollow body, side edges isosceles Triangles, the legs of which are planar mirrors made of sheet aluminum and / or other suitable ones Materials are formed and with the angle plumb alignment according to the position of the sun Absolutely best possible, shadowless illumination of the front and back the solar cells at an angle of 9o degrees is possible.

In practice, this maximum irradiation value is constantly attempted by a sun position approximation method, to be achieved by the prismatic Hollow body rotatably attached in the cathetus angle, by an electric motor and / or a spring clock moves, controlled by a light diode and electronics, the respective Sun position is closely approximated.

A further increase in current efficiency, in conjunction with prismatic Hollow bodies appear through the use of concentrating systems, for example Fresnel lenses as well as high-quality Galliun arsenide solar cells possible.

According to the requirements of practice, the solar cells can both Can be connected to the same or parallel to solar cell generators and / or in can be combined in a network.

The radiation-favorable arrangement of the solar cell generators in the prismatic Hollow body clearly predestines this for the composite.

Optionally, both the pivotable and / or rigid Frame shapes and / or tension wire structures built-in solar generators, as also the solar cell generators clamped in prismatic hollow bodies lateral wire pulls combined into blind-like, strip-shaped solar cell surfaces where the composite can be approximated to the position of the sun from one point.

The wire pulls can optionally consist of electrical cables and thus serve to record the current in the network.

Overall, thanks to the use of both the front and the rear of the solar cells for converting light into electricity, with a slight increase in manufacturing costs, a doubling of the irradiation area compared to conventional solar cells, by breaking up large, normal, rigid solar cell surfaces into strips, making it easier Alignment according to the position of the sun, enhanced by rotational movements that are favorable to the radiation and arrangements of the solar cell generators a significantly improved detection the daily incidence of light, as well as being cheaper to use thanks to the lightweight construction Planar mirrors, instead of expensive solar cells, from case baths and / or panels make expensive, rigid constructions cheaper solar cell generators and thus aimed for a higher degree of economic efficiency.

In the world there is an intensive research in the field of photovoltaic Solar cells, with the aim of reducing costs and increasing the efficiency of the solar cells.

A number of solar cell types are being tested or are in use. As a rule, the solar cells become planar and rigid summarized and placed at a favorable angle to the sun's rays again, who can withstand high temperatures and expect a high yield of electricity let, but are still very cost-intensive at the moment, are used in conjunction with concentrating Systems such as lenses or parabolic mirrors combined to form solar generators.

There is also a strong need to manufacture relatively inexpensive thin film cells work, but where the lifespan is still too little knowno the greatest reliability After many years of use, extra-terrestrial silicon solar cells have in the Achieved space travel.

In the known arrangement method for solar cells, the cost-effective, The sun-favorable mobility of the solar cell generators was assigned too little weight.

In none of these procedural arrangements will this be the solar radiation The opposite side of the solar cells is used to convert light into electricity.

With none of these procedural arrangements can a shadowless, inexpensive Arrangement of plane mirrors for cell irradiation can be achieved.

Above all, planar and rigidly grouped solar cell modules can only cope with the different angles of sunshine that can be expected on a daily basis through considerable additions Therefore, for all types of sun cells, sun-favorable, cheap Cell arrangements of great importance.

The object of the invention is therefore to create a method with which it is possible to increase the electricity yield of solar cells by using both the Increase the front as well as the back of the cell for the conversion of light into electricity by coating the substrate of heterogeneous semiconductor cells on both sides and / or bilateral diffusion of boundary layers onto the basic cell more homogeneously Semiconductors, according to known application methods and / or optionally their own arrangement the coating and / or its own boundary layer configuration and / or its own contact configuration to promote the conversion of light into electricity on both sides with less radiation Arrangement and economical lightweight construction of solar cell generators, consisting from solar cells with contacts, Power lines and reverse flow diodes, Reinforced in rope ladder-like fashion by wire and / or other suitable materials crystal clear sheath tapes and / or plates made of plastic and / or other suitable ones Materials, optionally in movable, swiveling and / or rigid frame shapes and / or Tension wire constructions built in, which provide better illumination of the solar cells allow 'excellent but clamped in the upper hypotenuse of prismatic Hollow bodies, sides are edged with isosceles triangles, the cathets of which are made of sheet aluminum and / or other suitable materials form plane mirrors with those in the case of angular plumb alignment according to the position of the sun, the absolutely most favorable, shadowless illumination the front and back of the solar cells at an angle of 9o degrees becomes possible.

In practice, however, attempts are constantly being made to achieve this maximum bed radiation value to be achieved by an approximation process by placing the prismatic hollow body in the Cathet angle attached rotatably, controlled by a light diode and electronics, through Electric motor and / or spring clock moved, strongly adapted to the respective position of the sun will.

According to the requirements of practice, the solar cells can also directly and / or in parallel optionally connected together to form solar cell generators will.

You can choose between movable, rigid and / or rigid Frame shapes and / or tension wire structures built-in solar cell generators as well as the solar cell generators clamped in prismatic hollow bodies lateral wire pulls can be combined to form a composite and louvre-like, strip-shaped ones Form solar cell surfaces, the network being controlled from one point, the position of the sun can be approximated.

The wire trains can optionally consist of electrical cables and thus serve at the same time to record the current of the network.

Optionally, a further increase in the electricity yield can be achieved through installation concentrating systems, for example Fresnel lenses in connection with high quality Galliun arsenide solar cells and / or other suitable systems in the upper Hypotenuse side of the prismatic hollow body take place.

This is achieved by using both the front and the back of the solar cells for converting light into electricity, with a slight increase in manufacturing costs and a doubling of the irradiation area compared to conventional solar cells achieved, while by dissolving large common areas of solar cells in strips Easier alignment according to the position of the sun, enhanced by favorable radiation Rotational movement and arrangement of the solar cell generators a much improved Detection of the daily incidence of light is achieved, as well as through lightweight construction, use Cheaper plane mirror instead of expensive solar cells, from sheath tapes and / or Panels instead of expensive rigid constructions make solar cell generators cheaper and thus a higher degree of economic efficiency is sought0 The stated task is there d u r c h g e 1 ö 8 t that by coating the substrate on both sides it heterogeneous semiconductor cells and / or bilateral diffusion of boundary layers onto the basic cell of homogeneous semiconductors according to known application processes a use of both the front and the back of solar cells for the conversion from light into electricity possible and / or optionally a promotion of this task through Own arrangement of the coating and / or boundary layer configuration described below and / or a contact configuration can be done by in heterogeneous semiconductors g so-called thin-film cells, the substrate is to be used as the middle layer this according to the individual manufacturing.

process a double-sided coating takes place. According to your own arrangements Fine molybdenum and / or aluminum sheets form the substrate and at the same time the Back contact of the solar cell, cut and / or according to the requirements punched so that easy contact is possible 0 The coating processes can usually be done on both sides at the same time.

This will greatly reduce the cost of the manufacturing process in the Ratio to possible irradiation area reached0 Optionally, more usual instead glued cover film, a seal of the solar cell and / or the solar cell generator done by quartz vapor deposition.

Only then is it installed in the sheath straps, as described below and / or sheets of plastic and / or other suitable material and or in the case of homogeneous basic semiconductor material, for example p-doped polycrystalline Silicon and / or other suitable material, n-boundary layers on both sides in strip form are diffused in such a way that a large p-doped basic cell (suggestion 14 X 14 cm) 80-85 percent of the n-boundary layer is provided between the strips Bars of undiffused base material remain and both on the p-doped Bars, as well as so-called contact fingers on the n-boundary layer according to known ones Procedures are opened to enable a bilateral p + n current draw.

Optionally, this arrangement can also be modified so that on the p-doped base material web and the associated n-Stromabnahnekontaktfinger again a thin electrical insulating layer is applied to this insulating layer over-lapping and over-lapping on the n-boundary layer, the p-Stromabnahnekontaktfinger is applied, so that a compression of the electricity is similar to that of a Condenser occurs and cell base area for irradiation is saved.

Whereby the contact configuration, the cca.2o percent of the cell front and Rear side can be arranged out of phase on the front side and the rear side of the cell that there is a partial reflection on about 40 percent of the total irradiated area the unabsorbed light can be used for better use.

With both arrangements, however, by dividing the basic cell into small ones Units, cell units, short current paths are created.

which favor a better power consumption, while the higher one Number of contact fingers, the ohmic series resistance is better balanced and duit the cell performance is increased.

And / or by coupling the p + n front and back currents of the solar cell , as provided in the arrangements and contact configurations (newspapers), a reduction the surface leakage currents can be expected at two edges.

Excellent, however, for both heterogeneous and homogeneous solar cells higher voltages and currents than a normal solar cell with only front light receptacle are to be expected and so improved options for the design of electrical Storage systems arise in weak sunlight.

And / or d a d u r c h g 1 ö 5 t that to promote both Conversion of light into electricity a radiation-favorable arrangement of solar cell generators in the case of economical construction is made by using clear plastic films and / or plates, and / or other suitable materials, but preferably made of Special polycarbonate films with the properties of long resistance to UV rays, a high light transmission up to 85%, great toughness, self-extinguishing and the electrical, good current creep behavior, temperature resistance between 40 degrees C and + 140 degrees C over a longer period of time, following the rope ladder principle thin wire and / or fiberglass reinforced, lining r a 1 bands and / or plates are made to accommodate solar cells of various types, optionally connected in series and / or in parallel to solar cell generators, where the solar cell generators consist of solar cells with power take-off contacts, Non-return valves, continuing power lines and connections, cover foils and / or seals, in contrast to other methods, completely independent Form units and sheath straps and / or plates only intended as a carrying device are glued, welded and / or optionally into the solar cell generator can be pressed in under vacuum. And / od-r optionally as the only solar cell function Antireflective layers can be applied to the sheath tapes so that antireflective layers Optionally, the cells can be omitted.

And / or the sheath tapes produced in this way and / or Plates with the solar cell generator as content optionally by further mechanical Additional devices can be better used by Extension of the cross reinforcement wires of the sheath tape. Training of eyelets at the edges of the sheath band, creating a sheath band shape that keeps its tension and fastening by tension wires drawn laterally into the eyelets and / or others receives suitable materials and is therefore suitable, optionally on these tension wires stretched, on masts similar to sails, as a solar cell generator for To serve flower beds, ships and / or other movable and fixed structures by converting sunlight into straw on both sides in different positions of moving objects to the sun, a higher one Probability of exposure to sunlight is given with the same space requirement. And / or optionally supported by the frames Sheath tapes with content as a flat and / or normal roof solar cell generator Use0 And / or alternatively the sheath straps with solar cell generation gates are rigidly clamped in frames, which are both permanent in a favorable Angle to the sun can be set up and / or hung, as well as accordingly stored in rotating and / or swiveling frames, optionally by manual control Spring clock and / or by an electric motor, controlled by a light diode with a corresponding Electronics can be approximated in their position to the respective position of the sun.
