The features of the photoconductivity
activation of the CdTe thin films by cadmium halogenides mixtures
Abstract
The effect of annealing temperature in the
presence of mixtures of cadmium chloride and cadmium iodide of different
composition on the electrophysical properties of CdTe thin films was studied.
This process, in which, as a rule, cadmium chloride is used, is called
“activation”. It allows you to significantly improve the efficiency of solar cells
based on CdTe. In this paper was found that it is possible to reduce the
temperature of this process from 450 to 300 °C by replacing CdCl2
with a mixture of the composition ~60 mol% CdCl2 to ~40 mol% CdI2.
Key words: solar cells, photoconductivity
activation, cadmium telluride, building integrated photovoltaics.
