The invention relates to electrical engineering, in particular to a device for generating electrical energy by light radiation into electric power and is intended for use in the construction of solar batteries (SB).

Known solar battery (Gunter la Roche, Solargeratoren fur die Raumfahrt, Braunschweig, Wiesbaden Vieweg, Germany, 1997, JSBN 3-528-06945-7)designed to provide power for spacecraft. SAT consists of solar cells (SCS)connected to each other with flexible inter-element connectors, and cell panels, the surface of which is formed by layers of carbon fiber and insulating material, between which is located a cellular filler of aluminum foil.

Electricity generating portion of the SAT (modules), consisting of a solar cell with a protective coating, is glued to the flat surface of the panel with elastic sealants, when this adhesive composition is applied in a continuous layer.

The signs of this design SAT, in common with the characteristics of the proposed SA, the following:

panels;

- SE, connected to each other with flexible inter-element connectors;

- Solar cell provided with a protective coating and bonded to the surface of the panel.

The disadvantage of SAT - analogue is the following:

- increased degradation characteristics of SB during operation, due to the presence of adhesive in the interelement promesed the x, which is subjected to sputtering due to the impact factors of electrification and subsequent deposition on the front surface SA.

technological difficulty of ensuring inter-element gaps at a label SE on the surface of the panels.

The closest and adopted for the prototype is SAT (GLOBASTAR. Solar Generator Desigh And Layout For Low Earth Orbit Application in Consideration Of Commercial Aspects And Quanlity Production. D-81663 Munich Germany), located on the carbon honeycomb. Supporting part cell panel consists of two layers of carbon fiber, between which is located a cellular filler of aluminum foil. On the carbon surface, designed for stickers SE, glued insulating film. Electricity generating portion of the SAT (modules) consists of a solar cell connected to each other through switching elements to thermo-mechanical expansion joints. On the front surface of each solar cell is glued to a glass plate.

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

panels with glued on them modules;

modules are composed of solar cell, in series or series-parallel connected to each other by switching buses to thermo-mechanical expansion joints;

to the front surface of each solar cell bonded protective glass plate;

modules are glued to the panels using e is a partial adhesive (sealant).

The disadvantages of the prototype is the following:

- high probability of damage to the inter-element switching, protruding over the front surface of SAT, in the process of its production and maintenance;

technological complexity of manufacturing inter-element switching, caused by the necessity of placing thermo-mechanical expansion joints in narrow inter-element gaps;

- technological complexity of guaranteeing inter-element gaps;

- limited SB resistance to the effects of thermal and mechanical loads, caused by a thin layer of elastic adhesive (sealant);

- high probability of the presence of uncontrolled defects in the adhesive layer (the so-called “bubbles”), due to its large area and limited thickness;

- limited ability stickers modules SAT on a curved surface.

Technical results achieved in the proposed SA, the following;

- increased durability SAT to mechanical and thermo-mechanical loads due to the assured elastic layer of sealant specified thickness and configuration.

the absence of adhesive in the gaps between SE and other elements of design, which significantly reduces the degradation of the electrical characteristics of the security Council during its exp is watachi and eliminates the need for cleaning inter-element gaps, at which the probability of damage to the inter-element switching;

- allows use of large SE on curved surfaces, which contributes to the improvement of the energy characteristics of the SAT;

- provides the possibility of placing a shunt (bypass) diodes on the back side of the solar cell is significantly easier than switching system and decreases the mass of the SAT;

- provides the possibility of placing thermo-mechanical expansion joints switching buses between the back of the AOC and the frame, which ensures reliable protection against mechanical damage during manufacture, and land use;

- provides even distribution of weight SAT on the surface of the frame;

- vkluchaetsia the possibility of formation of air voids (bubbles) in the hermetic, resulting in improved bonding and vkluchaetsia the possibility of damage to the solar cell during operation SAT in the conditions of space vacuum.

Achieved above-mentioned technical result is as follows: solar panel, consisting of a series or series-parallel connected solar cells and bypass (bypass) diodes, glued to a solid flat or curved surface, not the entire area, but only in the area bounded by an elastic element which is placed under each SE, in the case of the use of large SE for fastening may be used two or more elastic element. The elastic element is made in advance of the cured adhesive, which will be gluing SE to the frame. The elastic element may be made of any shape and size in relation to a particular design by pouring adhesive (sealant) in a special form. Elastic elements are bonded to the surface of the frame on the preliminary layout and the internal volume is filled with an adhesive (sealant) prior to the formation of a convex meniscus, the AOC pressed against an elastic elements and are fixed in a predetermined position prior to complete polymerization of the adhesive composition. The presence of a convex meniscus guarantees the necessary size of the bonding without forming closed cavities (so-called “bubbles”) with air. Available while a slight excess of adhesive evenly squeezed and remains in the form of the cuff between the back side of solar cell and an elastic element, without falling into the gaps between the solar cell. To ensure the mechanical strength of adhesive joints is usually sufficient to limit the area of the gluing 20-40% of the area of a solar cell. This allows to increase the thickness of the sealant without increasing its total mass and d the same with some reduction of weight of the sealant relative to the traditional version. The increase in the thickness of the sealant substantially increases the stability of the SAT to thermal and mechanical loads. In addition, the presence of cavities between the back of the AOC and cage-free sealant, allows you to place a shunt (bypass) planar diodes and thermo-mechanical expansion joints switching buses between the back of the AOC and the frame, thereby eliminating the possibility of damage when working with SAT.

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

- SAT contains glued to a flat or curved surface elastic elements having a specified shape and size;

- internal volume of the elastic elements is filled with a sealant prior to the formation of a convex meniscus;

- SE is pressed against an elastic elements and fixed on them;

switching tires to thermo-mechanical expansion joints and shunt (bypass) diodes, welded or soldered to the back contact solar cell in areas free from sealant;

- thermo-mechanical expansion joints switching buses are located between the back of the AOC and the bearing surface of the frame in areas free from sealant.

To prove compliance of the proposed SAT the criterion of “inventive step” was analyzed the totality of characteristics and each individual is distinctive about the signs. It is established that the application of the aforementioned character, which in conjunction with the known characteristics of the technical result consists in high SB resistance to mechanical and thermo-mechanical loads, to reduce the degradation of the electrical characteristics of the security Council in the course of its operation, in the possibility of using large SCS curvilinear surfaces, to simplify switching system and reducing the mass of SB, reliable protection from mechanical damage during manufacture and ground operation, a uniform distribution of mass SAT on the surface of the frame, as well as to improve the reliability of operation SAT in the conditions of space vacuum, in the literary sources are not detected.

Thus, according to the authors, the proposed SB meets the criterion of “inventive step”.
