parameters and light diode characteristics of film SCs based on cadmium telluride
2022 IEEE 3rd KhPI Week on Advanced Technology (KhPIWeek)(2022)
Abstract
The effect of electron radiation with a 75 keV beam energy on the stability of output and light diode parameters of solar cells based on cadmium telluride was studied. Two types of solar cells were considered, which differed by the cadmium telluride layer obtaining method: vacuum thermal evaporation or condensation in quasi-closed volume. It is shown that solar cells with a more structurally perfect layer of cadmium telluride, manufactured using the hot wall method, lose more efficiency. The main reason for the loss of efficiency for them is a decrease in the value of the photocurrent. After the irradiation influence for solar cells made by the vacuum thermal evaporation method, the efficiency does not decrease significantly. The modeling of the quantitative influence of the light diode characteristics on the efficiency made it possible to propose physical mechanisms of the evolution of the defective subsystem in the cadmium telluride layer after the electron irradiation influence, which could explain the observed changes in the diode and output parameters.
