Alternative power sources and their degradation resistance in the conditions of emergency situations of technogenic character

Abstract

The actual scientific and practical task of the sphere of civil protection is investigated in the work, namely the possibility of uninterrupted functioning of emergency counteraction systems in the conditions of limited power supply due to the use of alternative power sources.
In the course of solving the set scientific and practical problem, an analysis of the current state of solar cells for use as a backup power supply of emergency response systems. It was found that thin-film solar cells based on cadmium telluride (CdTe) p-type conductivity are promising solar cells in terrestrial applications.
They have the highest among single-pass photoelectric converters theoretical efficiency ¬ 29%.
To establish the duration of their use as a backup power supply for emergency response systems, the analysis of degradation resistance of SE based on cadmium telluride (CdTe) p-type conductivity was performed. It is established that after 8 years of operation the value of the efficiency of CE SnO2: F / CdS / CdTe / Cu / ITO almost coincides with the initial value, which indicates the high degradation resistance of the obtained heterosystems. Differences in the initial parameters and light-emitting diode characteristics of CE SnO2: F / CdS / CdTe / Cu / ITO under illumination from the glass substrate and from the transparent rear electrode, which are due to the influence of the rear diode on the efficiency of photovoltaic processes in the base layer.
