Abstract

Annotation. Today, the need for energy is the most pressing and urgent need in the world. Therefore, scientific approaches in the world place great emphasis on energy. Alternative energy sources play a key role in electricity generation. Nuclear power plants and thermal power plants are harmful in terms of safety and emissions to nature. To solve such problems, it is preferable to use alternative energy sources. Methods. In this article, it is necessary to obtain a semiconductor crystal material to generate alternative energy. In order to obtain such a semiconductor crystalline material, the main task in the article is to form zinc oxide nanorods to form a p-n transition layer. There are several ways to grow nanorods. These include: gas phase growth, laser light growth, fiber laser growth, chemical and hydrothermal growth. Gas-phase growth method: molecules that form nanorods in solution are sent by nitrogen or other gas, the energy is transferred by a stream of gas. In laser light, the energy given to a molecule is transmitted by laser light. The solution is energized using a pulsed laser beam. Chemically, the solution is heated in an autoclave for 5-24 hours. Results. In the work covered in the article, a hydrothermal method was used to grow zinc oxide nanorods. The advantage of using this method is its low cost and convenience in terms of equipment. At the same time it is difficult to find substances from cheap laboratory equipment and solutions. However, this method of hydrothermal cultivation is almost impossible to find and use in the laboratory and in solution. The samples need to be thermally processed by growing zinc oxide nanorods. Discussion. The article discusses methods and examples of growing nanorods to form organic heterostructures based on zinc oxide nanorods. The study synthesized zinc oxide nanorods hydrothermally grown at low temperatures. The study analyzed the structural properties of zinc oxide nanorods grown hydrothermally based on images obtained under a scanning electron microscope. Conclusion. On the surface of ITO trays, nanocrystalline buds of ZnO were formed by the spin coating method, and this method was found to distribute them evenly relative to the buds formed by the dip coating method
