Abstract

Investigations of solar cells based on CdS/CdTe, designed for reserve power supply of security systems and control of objects in conditions of damage to the power supply system, have been carried out. An analysis is made of losses in the initial parameters of solar cells based on cadmium telluride, which are due to the design features of the device structure and photoelectric processes occurring in their volume upon absorption of light. Implemented approaches to increasing the efficiency of a photocell based on CdS/CdTe and their effectiveness are studied. Ways are proposed to increase the efficiency of such film solar cells by improving the method of obtaining a rear contact. Design and technological solutions for SC ITO/CdS/CdTe/Cu/Au have been developed, which make it possible to obtain laboratory samples with an efficiency factor of more than 10 %. Laboratory samples of ITO/CdS/CdTe/Cu/ITO CEs have been fabricated, the two-sided illumination
of which makes it possible to increase the electric power by 30 %. The research of Cu/ITO transparent rear contacts for CdTe-based solar cells intended for use in tandem and bilaterally sensitive device structures have been studied. The study of the light Current-voltage characteristics of SnO2:F/CdS/CdTe/Cu/ITO solar cells under illumination from both sides made it possible to establish significant differences in the initial parameters and light diode characteristics under illumination from the side of the glass substrate and from the side of the transparent rear electrode. Testing of laboratory samples of ITO/CdS/CdTe/Cu/ITO solar cells as part of tandem photovoltaic converters has been carried out. Research has been carried out on methods for obtaining CdTe base layers for creating efficient solar cells on a flexible substrate. With a series connection of ITO/CdS/CdTe/Cu/Au SC, experimental samples of micromodules with an efficiency of 5.4 % have been obtained.
