Also, a calendar-thematic plan of a physics circle was developed to develop the technical creativity of students based on alternative energy sources, the possibility of developing technical creativity of students on the example of a project to provide energy at home based on solar panels. technical creativity, circle activity, alternative energy sources, device, design, solar panel Introduction Today, there is a need to use the latest information so that the product of technical creativity is at the level of modern requirements. Therefore, in the process of mastering the technology of creativity, in addition to informing students about the latest achievements of science and technology, one of the topical issues is to familiarize them with socio-economic, environmental and energy problems [3, p. . 177]. When using devices of alternative energy sources in the development of technical creativity of students in physics lessons, it is necessary to pay attention to the following: - Draw students' attention to the possibility of using technical goals in physical phenomena and processes of the device under study; - Providing students with examples of the use of alternative energy sources in everyday life; - Conducting a discussion on topical issues in everyday life, technologies of use in the presented material; - Orientation towards the integration of practical work with the studied materials in physics using devices of alternative energy sources; - Organization of training using technical documents, animations of devices, visual aids, layouts and models, equipment and tools available in the laboratory; - Prospects for the development of technologies for alternative energy sources, research conducted in this area, presentation of achievements achieved using modern methods and technologies, holding round tables with the participation of industry scientists [5, p. . 266].

To do this, first of all, it is necessary to know the electrical conductivity of semiconductors, their structure and the connection of atoms with each other, their chemical properties. In this case, it is necessary to recall the knowledge gained by students in chemistry. There are many ways to use solar energy, one of which is to generate electricity using semiconductor solar cells. [1, p. 143] . The process of converting solar energy into electricity is carried out due to the photoelectric effect. It is formed in the form of free electrons with a thickness of 2-3 microns in the surface layers of semiconductors. When free electrons appear on the surface of a semiconductor and there is a difference in Figure 1. The process of generating electricity in a silicon solar cell. American Journal of Research in Humanities and Social Sciences Volume 4, Sep., 2022 P a g e | 29 www.americanjournal.org electric potentials, an electric current arises in it. The potential difference between the emitting surface and the shadow side of the semiconductor arises due to the introduction of special additives into its surface layers. One of the additives ( n- type) creates additional electrons and a negative surface charge, and the other ( p- type) creates a lack of electrons, i.e. a positive charge (Fig. 2). Silicon solar cells are mainly used. Silicon is the most abundant element on earth. Elements are obtained by melting silicon and then growing crystalline silicon in the form of a sterlet with a diameter of 5-10 cm. To obtain direct semiconductors, these rods are cut into thin plates with a thickness of about 300 microns. They are the main part of photovoltaic cells. The manufacturing technology of solar cells is as follows: by installing a silicon wafer in a high- temperature electric furnace, it is heated p or n a type of semiconductor material is introduced into a vacuum by diffusion [4, p. 128] . The main advantages of solar panels are large FIC, long- term operation, simplicity, high specific power (the ratio of power to the mass of the cell), but relatively high cost and the need for an additional energy source are one of the disadvantages of solar panels (Fig. 2 ). When using semiconductor photocells as solar cells, knowledge of the spectral structure of solar radiation is one of the main aspects of the issue [2, p. 83] . Therefore, it is necessary to select a semiconductor material knowing the optical properties of the semiconductor, which indicate which parts of the solar spectrum can be used in the manufacture of a solar cell, and electrical properties, which describe the ability to efficiently convert the sun's rays. energy into electricity. Students are taught to first use a computer program to draw a project for providing electricity to the house based on solar panels (Fig. 4). After the project is ready in a computer program, it will be possible to make a model based on it. It is possible to show the possibility of using alternative energy sources in the development of technical creative competencies of students [6, p. 195]. Figure 3.

It is important for them to become specialists in the field of technology. REFERENCES 1. Хайриддинов Б., Содиқов Т., Нуриддинов Б. Ўрта мактабда гелиотехника элементлари. –Т.: Фан, 1995. – 192 б. 2.
