Study of Methods for Producing Flexible Solar Cells for Energy Supply of Emergency Source Control

Abstract

The methods of obtaining the base layers of cadmium telluride to create effective solar cells are considered. At present, two groups of methods are distinguished for the preparation of base layers of cadmium telluride for high-efficiency PECs: low-temperature and high-temperature. If a polyimide film with a temperature stability of 450 °C is used as a substrate, then deposition should be carried out at a temperature of about 430 °C. Therefore, to create base layers of cadmium telluride on a flexible polyimide substrate, it is necessary to use low-temperature methods for producing base layers. It has been established that the formation of base layers of solar cells based on cadmium telluride on flexible polyimide substrates must be carried out by direct current magnetron sputtering.
