The invention relates to electrical engineering, in particular to a device for generating electrical energy by converting the energy of light radiation into electrical energy, and is intended for use in the construction of solar batteries (SB)containing the flat panels, the frames are made of carbon fiber tubes or other structural materials of a certain profile.

Known SB (1)designed to provide electrical power to the space station and space platforms. SAT consists of panels that are stacked during transportation in containers with damping pads. Energy-generating part of the SAT consists of solar cells (SCS) of the silicon size 80×80 mm, a thickness of 200 μm with a coating front contact, placed on the back surface. SCS are bonded to the carrier substrate, consisting of two layers of polyimide film with a thickness of 25 μm with located between them a reinforcing layer of fiberglass. Switching SE by contact welding using copper switching buses, which are affixed to the substrate between two layers of polyimide film.

The disadvantages of this design are the technological complexity of manufacturing the substrate, lack of reliability of the adhesive joints of the AOC and the substrate is insufficient for isinnet SE from the appearance of cracks during operation, and low maintainability SAT in General.

Features common to this design SAT with signs proposed SB, the following:

panels;

- solar cells;

- film substrate, to which is glued SE;

- implementation connection SCS using switching buses.

The closest and adopted for the prototype is SB (2), consisting of a skeleton in the form of flat panels with evenly spaced cells and with mounted modules, consisting of a series or series-parallel connected solar cell attached to a perforated film substrate using a rear glass plates and perforated film substrate has a tape tabs, designed for fastening the module to the frame SB, with the tape tabs are evenly spaced around the perimeter of the module and perforated film substrate made of reinforced polyamide film, and solar cell connected between a switching tires with compensatory curves.

The disadvantage of the prototype is:

- low manufacturability and operation, due to the impossibility of repair SAT, as when removing the module from the frame it is necessary to make the destruction of the adhesive bonding tape tabs, which leads to their damage or rupture. Further use is of the modules. In addition, there is the difficulty of constructive alignment of adjacent modules in the composition of the panels, as the tape tabs to secure the pipe in the middle of the panels opposite divorced in space and enters an area adjacent modules;

low reliability SB, due to the need to organize a special switching elements connecting peripheral solar cell in an electrical circuit with the organization of attaching them to the elements of the module that creates the preconditions for their failure.

The characteristics of the prototype, in common with the characteristics of the proposed SA, the following:

- SAT consists of a frame with evenly spaced cells and with installed modules;

modules consist of a series or series-parallel connected with switching buses with compensatory curves of solar cells;

- Solar cell bonded to a perforated film substrate using a back plate;

- perforated film substrate made of reinforced film, and has a tape tabs for attaching the module to the frame.

The technical result achieved in the proposed SA, is to improve the manufacturability and operation of the SAT in combination with high reliability due to the following:

- simplification of constructive alignment of adjacent modules in SOS is the ava panel SB;

- no special switching elements (tires)connecting peripheral solar cell in an electrical circuit;

- ensuring the free surface of the frame SAT.

This is achieved by the fact that in SA, consisting of a skeleton in the form of flat panels with evenly spaced cells and with installed modules, consisting of a series or series-parallel connected switching tires with thermocompensation bend SE attached to a perforated film substrate using a rear glass plate, made of reinforced film and having a tape tabs for attaching the module to the frame, these tape tabs are mounted the elements of the mortgage in the form of segments of conductive spokes. While fastening the modules to the frame of the yarns, fixed on the fixing elements. In addition, the adjacent solar cell is connected in the electrical circuit on the periphery of the module by connecting an elastic switching buses with thermocompensation bend with packing elements.

If necessary, you can easily remove the module from the frame without damaging it by cutting threads of the mounting with its subsequent re-Assembly into place.

When mounting adjacent modules in the middle part of the frame threads are easily bred in space.

Use the bookmark is the breaking of the elements of the dual-use eliminates the need for additional switching elements and the associated probability of breakages circuit and short circuit.

Distinctive features of the proposed SA, ensuring its compliance with the criterion of “novelty”, the following:

- mounted in the tape tabs perforated film substrate embedded elements, made of segments of conductive spokes;

- fastening of the module to the frame threads fixed to the mortgage elements;

- adjacent solar cell is connected in the electrical circuit on the periphery of the module by connecting an elastic switching buses with thermocompensation bend with packing elements.

To prove compliance of the proposed design SAT the criterion of “inventive step” were analyzed the totality of the signs and separately distinguishing features. It is established that the application of the aforementioned character, which in conjunction with the known characteristics of the technical result consists in increasing the manufacturability and reliability of the SAT, in the literary sources are not detected. Thus, according to the authors, the proposed design of the SB meets the criterion of “inventive step”.

The proposed SB schematically depicted in figure 1 and 2.

Figure 1 shows the individual flat panel consists SAT. The panel contains supporting frame 1 composed of cells 2, each of which has a module 3 (Fig 1, a). Module 3 sostoi is from SE 4 (figure 1, in), the front 5 and rear 6 glass plates, perforated film substrate 7 with the tape tabs 8, spaced evenly around the perimeter of the module 3 and in which are mounted the elements of the mortgage from pieces of a metal conductive spokes 9 (1)providing a sequential switching circuit between adjacent solar cell 4. SE 4 connected with each other and with spokes 9 elastic switching metal tire 10 having thermocompensation bend 11 (figure 1, b; e). AOC 4 is fixed in the module 3 on the substrate 7, located between the solar cell 4 and the rear glass plate 6 through a perforation in the substrate 7 (Fig 1, b; e).

Figure 2 shows the appearance of the module is ready for installation on the frame.

Module 3 is fixed on the frame 1 by threads 12, the ends of which are bonded to the frame 1 (Fig 1, e). The rack 13 of insulating material (Fig 1, b) are bonded to the frame 1 with a step equal to the distance between the tape tabs 8 on the module 3.

A specific example of the construction of the proposed SAT.

The proposed SB consists of a flat rectangular panels of size 1600×3200 mm, frames 1 which are made of carbon tubes with a diameter of 25 mm Each panel is divided into 16 cells 2 size 400×800 mm each. In each cell 2 is set to module 3 with dimensions 387.4×785.8 mm, containing 138 is e 4 size 33× 63.5 mm, connected in series with the switching of silver tire 10 with thermocompensation bend 11. The substrate 7 is reinforced with fiberglass polyimide film with a thickness of 100 μm, which is located between the back side of solar cell 4 and the rear glass plate 6. The fastening of the solar cell 4 is made by gluing the back of the glass plate 6 to the back side of the solar cell 4 through a perforation in the substrate 7 with an elastic silicone rubber SCTP (TU 38-103-129-77). On the front surface of the solar cell 4 is pasted glass plate 5. In cells 2 modules 3 pinned threads 12, the ends of which are glued to the frame 1 by the adhesive BK-9 (OST 92-0949-74, PI A-99). When fixing the modules 3 on the frame 1 is provided by the condition of uniform tension of the threads on the perimeter of the module.
