ANALYSIS OF THE THERMAL STABILITY OF SOLAR CELLS ON A FLEXIBLE SUBSTRATE INTENDED FOR BACKUP POWER SYSTEMS EMERGENCY PREVENTION

Abstract

The effect of temperature on the output parameters of the ITO/CdS/CdTe/Cu/Au film solar cell on a flexible substrate, intended for use as an autonomous power supply for emergency prevention systems, has been investigated. It has been shown that a solar cell on a flexible substrate based on cadmium telluride with a Cu/Au back contact can be operated without a decrease in efficiency up to a temperature of 45оС. At higher temperatures, deterioration in diode characteristics is observed, due to a decrease in the value of the dark shunting electrical resistance and an increase in the value of the dark density of the diode saturation current
