The invention relates to the field of electric power industry, more specifically to renewable energy sources, and is designed to convert solar energy into electrical energy.

There are different types of solar panels that convert solar energy into electrical energy. There are many individual elements that directly converts solar energy into electrical energy, set closely to each other, forming a flat surface (panel) solar panels.

For example, the famous invention: U.S. Pat. 2127008, Russia, IPC H01 1.31/05; U.S. Pat. 2133415, Russia, IPC H01 1.31/042; U.S. Pat. 5647915, USA, IPC E04D 13/18. In these inventions individual elements that convert solar energy into electrical energy, are situated in one plane, forming a single-layer panel, which converts the energy of sunlight falling on the area of their surface, into electrical energy.

The aim of the invention is a method and apparatus for creation of highly efficient solar panels, which will produce a greater amount of electrical energy compared to existing solar panels in the same space of the surface. In the present invention may apply the same standard elements, which are used in existing solar cells.

To achieve the ate on the way to create high-performance solar panels, consisting of separate elements and occupying the same surface area as the existing flat solar panels, according to the invention is used volumetric arrangement of elements, making use more elements, direct solar energy inside the volume of the solar battery, carry out some accumulation inside this volume, which ensures that a high flux of solar radiation on each element, while the air (gas)inside the volume used for scattering of solar energy and for cooling of the solar cells to the optimal temperature (citing this air circulation and passing through a refrigerator), when they produce the greatest amount of electrical energy.

To achieve this goal in the device to create high-volume solar panels in the first embodiment, consisting of separate elements occupying the same surface area as the existing solar panels, according to the invention items (bilateral) there are space and form like several "packages"that are nested into each other, each of which uses a multi-layered arrangement of elements so that each layer elements are not closely, and at some distance one from the other, for example, in a checkerboard pattern, forming blank portion not occupied by the elements, and the layers themselves are parallel to each other so that the elements of the next layers are displaced relative to each other and are located opposite the space is not occupied by elements of the adjacent layer, wherein the lateral surfaces of the solar battery at some angle to them installed rails mirrors that direct incident sunlight to the inside volume of the battery, in addition, on the side surfaces, the reason solar panels are installed semi-transparent mirror or film, forming a closed volume, and the inner space of the volumetric solar panels is filled with air (gas).

In the device to create high-volume solar battery according to the second variant according to the invention items (bilateral) there are space and form a "package", "package" is used in a multilayer arrangement of elements (bilateral) so that each layer forms a flat panel, consisting of tightly docked items (bilateral), with volumetric battery may consist of a single "package" arranged in parallel layers, and guides the rays of the sun mirror can be placed with one, two or simultaneously with four side surfaces, when it is semi-transparent mirror (film) installed on all side surfaces of the bases, or two "packages", with a layer of the second "package" is located in the space between the layers of the first "package" perpendicular to these layers, guides mirrors are located on the sides, which surface is perpendicular to the layers of the second "package"and the semitransparent mirror (film) are installed on all side surfaces of the grounds.

In the device to create high-volume solar battery according to a third variant, consisting of separate elements occupying the same surface area as the existing solar panels, according to the invention used bilateral solar cells that are arranged in a "honeycomb", form a three-dimensional structure of polyhedral prisms, mirrors directing sunlight inside the volume of the battery can be located on both end surfaces of the horizontal battery, directing the sun's rays inside each of the individual prisms, and the semitransparent mirror (film) are installed on all side surfaces of the bases, or when located vertically battery its top end design without mirrors constantly focused on the direct sun rays inside the prism, and a second end, located at the bottom, is closed by a mirror that reflects the sun's rays inside the spacecraft the DOI of the prisms, this semi-transparent mirror (film) installed on all side surfaces and the upper surface of the base.

The goal is to create devices volumetric solar panels is achieved as follows (Fig.1-6).

Used volumetric arrangement of elements, for example, in the form of a cube or a parallelepiped, which can be formed by one (1), two (2) or more (3) "package" elements, which are nested within each other.

Figure 1 schematically shows a solar cell, forming a "package", which consists of individual layers, parallel to each other (figure 1 layers 1). Moreover, the elements 2 in the layers are not closely, and at some distance from each other, for example, in a checkerboard pattern, forming blank portion 3 not occupied by elements.

Figure 2 provides a diagram of the volumetric solar panels, consisting of two "packages" with mutually perpendicular layers. Here (as in Fig.1) 1 - horizontal layers of the first "package", 2 - elements of horizontal layers of the first "package", 3 - empty plots of horizontal layers of the first "package"4 - elements of vertical layers, which together form a second package with vertical parallel layers and which is perpendicular to the horizontal layers of the first "package". Moreover, the elements 4 of the second "package" feature is implemented in the empty sections of the 3 layers of the first "package".

Figure 3 provides a diagram of the volumetric solar panels, which may consist of three or more "packages". Here 1 - horizontal layers of the first package 2 - elements of horizontal layers of the first "package", 3 - empty plots of horizontal layers of the first "package"4 - elements of the vertical layers of the second "package", 5 - elements, the vertical layer, which together form the third package. The 5 elements of the third package of overlap with the elements 4 of the second "package". The vertical layers of the third "package" is perpendicular to the layers of the first "package". 6 is a mirror placed at an angle to the edges of the solar battery and guides the incident solar energy inside solar panels. 7 is a semi - transparent film or a mirror that is installed on all facets of solar panels and forms a closed volume in which there is a solar battery. When the mirror surface is directed inside the volume. Figure 1 and figure 2 for simplicity, not shown, guides the mirror 6 and the translucent film (mirror 7).

Thus, each "package" consists of a multilayer spaced elements. The elements in the layers are not closely, and at some distance from each other, for example, as noted, in a checkerboard pattern, forming blank portion not occupied by the elements. The layers in each "package"are arranged parallel to each other, and the elements of the next layers are shifted relative to each other and are located opposite the space is not occupied by elements of the adjacent layer (Fig.1). If there are two "package"layers "packages" are mutually perpendicular (figure 2). When using three or more "packages" layers of these "packages" perpendicular to the layers of the first "package", the surface of which is oriented to direct sunlight and the elements of the second, third, etc. "packages" intersect, forming an "cell" of the intersecting elements (Fig.3).

As noted on the sides of volumetric solar panels, inclined thereto are set mirror 6 (3)that direct incident sunlight inside solar panels along its entire height. (Figure 1 and figure 2 are not shown.)

In the internal volume of the solar battery is air (gas).

On the surface of the individual elements, not employed by a layer of directly converting solar energy into electrical energy, done a number of holes, the diameter of which is equal to the wavelength of incident solar beam or made diffraction grating, through which the sun's rays giragira and get on the elements of the next layer (not shown).

On the lateral surfaces and the surfaces of the bases of the solar battery is installed translucent film or mirror 7 (is), the mirror surface of which is directed inside the solar battery, and which form a closed volume, which is located inside the battery. (Figure 1 and figure 2 are not shown.)

We offer the option of solar panels in the same space, surface, and that the existing flat solar panels, and performed using the same standard elements will produce more electrical energy compared to existing due to the following.

First, the number of cells that convert solar energy into electrical energy, this volumetric solar panels is much larger than the existing flat batteries. Respectively, produced by the total electric energy elements volumetric solar panels will also be much greater than the sum of the electric energy generated by the elements of existing flat batteries.

Secondly, for each volume element of the solar batteries will get more solar energy compared with existing batteries, because:

inside solar panels along the entire height of fall of the solar rays reflected from the mirrors located obliquely to the side surfaces of the battery;

- semi-transparent mirror or film, which is installed on all faces of the outer surface of the Sol is echnol battery, and whose mirror surface is directed to the inside of the battery, transmits sunlight only inside the battery, and in the opposite direction they are reflected from the mirror surface and return inside, which contributes to the accumulation and increase of solar energy within the volume of the solar battery;

- on the edges of the elements and small holes (or diffraction grating of these elements) the sun's rays will be diffracted and get the following layers;

air (gas)in the amount of solar panels, scatters solar energy and promotes the penetration of solar energy on all elements within the solar battery.

Thus, the total flux of solar energy falling on each element in the bulk solar battery, much more compared to existing, and respectively produced by each element, the electrical energy will also be more.

Thirdly, the air inside the solar battery is used also for cooling the battery cells to the optimal temperature at which is produced the greatest amount of electrical energy, and maintain this temperature. For this purpose, the air is forced to circulate by a blower (not shown), is passed through the fridge (not shown) and cooled again to get inside the solar is th battery.

It should be noted that the three-dimensional arrangement of elements allows you to use double-sided solar cells, which allows for the same intensity of incident light to increase the output electric energy from one element compared to unilateral elements that are used in existing flat solar panels.

Another, simpler way to create a volumetric solar battery other than the above, is that in the "package" is used in a multilayer arrangement of the double-sided elements so that each layer forms a flat panel, consisting of tightly docked bilateral elements. This large solar panel may consist of one "package" with several parallel-arranged layers (Fig.4), or two "packages" with several mutually perpendicular layers (figure 5), in which there are no empty areas 3. When there is only one "package", the mirror, directing the sun's rays inside the solar battery can be located with one, two or simultaneously with four sides (Fig.4 not shown). When using two "packages" elements of the layers of the second set are located in the space between the layers of the first "package", perpendicular to them. It is evident from figure 5. Here 1 is the horizontal layers of the first "package" uh what elements 2, which docked with each other closely. 4 elements - vertical layers of the second "package", which is perpendicular to the layers of the first "package". In this case, directing the sun's rays mirror 6 are arranged on the lateral surfaces, the plane of which is perpendicular to the layers of the second "package", i.e. two sides of volumetric solar panels.

You can consider another way to create a volumetric solar panels, different from the previous ones by the fact that bilateral solar cells are arranged in a "honeycomb" 8 (6), forming a three-dimensional design from docked to each other polyhedral prisms, side surfaces of which are bilateral solar cells. This solar panel can be positioned horizontally (not shown)and vertically (figure 6). When the horizontal location of the battery mirrors directing sunlight inside the volume of this battery are located on the both end surfaces. With a vertical arrangement of the battery its upper end, without a guiding mirrors, constantly focused on direct sunlight, and the second end, located at the bottom, is closed by a mirror 6 which reflects the sun's rays, inside each of the prisms.

Thus, three-dimensional solar battery (and its various versions) to be effective and to produce far is about a greater amount of electrical energy compared to existing solar panels with four components: a larger number of elements with the same footprint surface; the use of bilateral solar cells; more solar energy incident on each of the elements; cooling elements to the optimal temperature at which is produced the greatest amount of electrical energy.
