The invention relates to an Autonomous power supply using the power of the Sun. In known constructions of photovoltaic modules as a filler - adhesive connecting surface panels (OP) with front and back protective coatings, has been widely used for cold-curing elastomers based on low-molecular siloxane rubbers with different side groups (U.S. Patent No. 4170507). Significant disadvantages of such aggregates, as well as materials described in U.S. Patent No. 3957337 are low process productivity due to long curing, low adhesion of the fillers to the surfaces of FP and glass, leading to the necessity of applying additional processing of the adhesion promoters, and the heterogeneity of curing in a relatively thick layers, as well as the possibility of occurrence of delaminations (Alipov) during long-term operation due to shrinkage phenomena. There are also variants of designs of photovoltaic modules, in which a filler module is optically transparent neutral polymethylsiloxane liquid (Patent RF №2205472). The closest in technical essence of the present invention is the RF Patent №2130670. This patent proposes a method of manufacturing a solar photoele the electrical module, including accommodation commutated of solar cells between two layers of glass, joined together on three sides on the ends by welding or bonding to the glass, heating the module to 50-80°S, filling optically transparent neutral fluid, the sealing glass by welding or bonding, and cooling to room temperature, and the optically transparent fluid is used polymethylsiloxane liquid. The disadvantage of the prototype method is the need for substantial compensatory amounts due to the almost linear dependence of the volumetric coefficient of thermal expansion of industrial brands polymethylsiloxane liquids on temperature. (Sobolevsky M.V., etc.. Oligoaniline. Properties, production, application. - M, Chemistry, 1985). The sealing module manufactured in accordance with the proposed in the prototype method, imposes severe restrictions on the choice of appropriate grades polymethylsiloxane liquids, in particular, molecular weight and thorough cleaning from low molecular weight impurities, the active selection which at temperatures above 60°can lead to the destruction of air-tight structure. The disadvantages of solar photovoltaic modules manufactured is on the way - the prototype should include the fact that any violation of sealing, for example, when the violation of the integrity of the glass, leading to leakage of liquid filler. This leads to the violation of optical and thermal contact between the surfaces of solar cells and glass and, consequently, to reduce the output electrical parameters. To the same effect leads and seal design on the perimeter. In addition, the placement of connected chains of solar cells and fixation of their location in the finished glass, in which the width of the gap between the plates is comparable to the thickness of the OP, it seems difficult to implement in practice, especially in the manufacture of modules of large size. The task of the invention is to increase the resistance of the PV module to seal the internal cavity of the module, the improvement of operational properties of the infill material (to increase the adhesion of the filler with the surface of the glass) while maintaining the level and long-term stability of optical characteristics, as well as the simplification and reduction of the manufacturing module. In use of the present invention increases the service life of the module and the stability of the output electric parameters throughout the term e is decommission. The above result is achieved by the fact that solar PV module consisting of two tightly glued on the ends of the sheets of glass, between which is placed can switch the panels, these panels are immersed in an optically transparent silicone fluid which is a mixture of polysiloxane containing dimethyl - or (and) Diethylenetriamine links, platinum catalyst and a crosslinking agent, and forming in the manufacturing process of the module semi-structured gel. In the proposed method of manufacturing a photovoltaic module can switch the panels with the current terminals is placed between two panes of glass, glued together on three sides using any glue with a heat resistance of not less than 50°With (depending on the selected mode of structuring), after which the assembled package fill optically transparent liquid which is a mixture of polysiloxane containing dimethyl - or (and) Diethylenetriamine links, platinum catalyst and a crosslinking agent, which by heating to 50 to 150°converted into low-modulus gel. The duration of the process depends on the selected temperature. A wide range of possible source components and a wide range of possible modes of the structure is tarirovanija allow to obtain gels - placeholders, long efficient in the temperature range from minus 80 to plus 260°With, without corrosive impurities and internal mechanical stresses. Formed the structure of the infill material has a high adhesiveness to the basic materials module (solar cells, glass), low elastic modulus, but lacks fluidity. The structuring process occurs without allocation of low molecular weight products and without shrinkage phenomena. Free (fourth) side of the perimeter of the glass may be sealed using any weatherproof adhesive - sealant to prevent contamination free surface of the gel during operation. One of the two or both silicate glass, depending on the desired stiffness and linear dimensions of the construction, may be replaced by sheets of optically transparent to the working surface of the module) permanent plastic. As one or both of the glasses use a sheet of weather-resistant optically transparent (for work surface module) polymer material. As one or both of the glasses use inorganic sheets of tempered or toughened glass. The essence of the invention illustrated by the drawing, which shows a General view of the photovoltaic module. Solar fot the electric module contains connected the solar cells 1, the glass sheet 2 from the side of the working surface on which incident solar radiation, the glass sheet 3 from the back surface of the module, optically transparent low-modulus gel 4, filling the free space within the module and between the panels and glass. A method of manufacturing a photovoltaic module is implemented as follows. On one of the sheets of glass (usually on the "back") record connected the panels. The output current terminals beyond the glass (preferably with one hand). A sheet of glass with solar cells connected with the second sheet of glass on three sides, providing the necessary clearance and tightness. With a free hand poured in the gap between the glass optically transparent liquid so that it fills the gaps between the panels and the free space between the surfaces of solar cells and glass. Carry out the heating module to the required temperature, the shutter speed at a given temperature and cooling to room temperature.
