Abstract

The article highlights the ways of organizing the research work of students at school and introducing the younger generation to research work, mobilizing and developing their creative abilities. The student was offered the orientation of the supervising teacher's work, the necessary criteria for determining research methods for students. The analysis of students' research work is carried out on the example of a scientific project that took the second prize at the republican stage of the republican competition of scientific projects in general education subjects. The results of obtaining silicon nanowires by the simplest methods, which are of great importance in the national economy and meet modern requirements in accordance with the subject of scientific research and the study of their properties, are analyzed. In the production of silicon nanowires, a chemical etching method was used, in which a simple metal was introduced, which could be made manually by the students themselves. The results of the research and analysis of the process of obtaining Silicon nanowires by students using this simple method, carried out in different time periods, were presented. It has been proved that the dependence of the lengths of silicon nanotubes on the time of chemical etching is linear. Based on the results of the analysis, tables and diagrams were presented. As the thickness of the silicon nanowire layer increases, its ability to reflect light decreases sharply, which means that the absorption property increases, which is very important for the absorption of solar energy. The article carried out within the framework of the study of the most important properties and production of silicon nanotalks described in the scientific work, conclusions and recommendations were made on obtaining cheap and environmentally friendly, cost-effective energy
