ABSTRACT
Today's concepts about solar elements (SE), batteries and photoelectric devices have historically appeared more than 40 years ago, and for the last 10-15 years they have entered the national economy as a source of energy and the marriage of ordinary people. The essence of the operation of these devices is based on the absorption of solar radiation in semiconductor materials and the separation of the resulting charge pairs in the potential barriers formed in the semiconductor and the processes of transmission to the external electric chain.
Keywords: solar elements (SE), semi-conductor, insulation, controller, accumulator battery.
Methods: As a result of fundamental Research in the early period, the full spectrum of solar radiation. the dependence on the property of the material to ensure its absorption was determined. In the Material volume, it was determined that the absorbed radiation can form charge pairs, and the process of their separation is a potential barrier (R - P transition) formed inside the semiconductor material and is dependent on the material properties. This made it possible to optimize the parameters of solar elements.
Practical studies were devoted to the design, preparation of QE structures with optimal parameters, the study of their properties, the development of the technology of QE, batteries and photoelectric devices and on their basis the implementation of the production of power supply systems with different structures, working in different conditions, designed for different power consumers.
The present - day QE is produced from a variety of semi - conductive materials depending on what conditions it is used (in the universe, Earth conditions, direct falling solar radiation, concentrated solar radiation, for extreme cases, etc.). Most of the QE, which is currently being produced and used as a source of electricity for human extyology, is made of silicon material. The main reason for this, the basis of the microelectronic devices, which are now widely used for folk medicine extyology, is Silicon. Secondly, silicon is an elementary semi-conductor, it can make up about 30%of the Earth's content, as well as in the development of its technology.

Solar elements (QE) are made mainly on the basis of semiconductor (NAO) materials. Therefore, QE requires knowledge of optical and photoelectric properties, the structure of YAU materials, their differences from metals and dielectric materials, and the study of properties that are directly fundamental to YAU materials.
We consider the formation of solid bodies from the point of view of the nuances of the electronic theory on the example of YAU materials. In the process of formation of a solid body, the approximation of atoms relative to each other goes to this level, as a result of which the generalization of electrons in the outer shell is formed. Instead of individual orbits of individual electrons in the atom, generalized collisions are formed, and the shells in the atom combine into spheres, and they generally belong to the Crystal. The nature of the movement of electrons changes absolute, the electrons located in a known Atom and at a certain energy level will be able to move to another army atom of the same energy level without changing the energy of the electrons and, consequently, will be able to freely shake the electrons in the Crystal.
The inner shells of all atoms in the isolation state of the Crystal are filled with electrons. Only in the area where the valence electrons are located, which consists of some of the highest levels, the levels will not be occupied by the scan. The electrical conductivity, optical and other properties of the Crystal are largely determined by the degree of saturation of the valence sphere and the energy distance from it to the sphere above, which is called the field of conductivity. On account of heat and optical excitation, electrons can pass through the valence field to the field of conductivity and participate in the transfer of electrical current. The empty spaces formed in the valence field form the displacement of electrons, the motion of the positive charge, which is dependent on it, and these charges are called holes.
Dielectric deb, valence field filled and after this field. the energy distance from the field of conductivity to it is said to substances that are relatively large. And metals have a different structure. In them, the valence sphere will be partially filled, or it will be intertwined with the next sphere-the conductive sphere.
When creating a mobile and renewable uninterruptible power supply device, we will consider the function of the accumulator battery charge control blog in charging the accumulator battery from the solar panel. The voltage coming out of the solar battery is around 21-23 Volts in the case when the charge is not connected, that is, the charge is around 17-18 volts when the accumulator battery is connected. This is the control of the accumulator battery charge when charging the accumulator battery from the solar panel Our Blog controls the voltage coming from the solar panel so that the charge for the accumulator with the voltage of 12 volts holds at miqdarini 13 volts. For this purpose,
