Abstract.
Shown in this work is the possibility to create industrial technology for
production of solar cells FTO/CdS/CdTe. The technology includes annealing in freon
processing step for activation of cadmium telluride base layers deposited by thermal
vacuum evaporation. Solar cells with efficiency of 7% have been obtained. Structural and
morphological researches allowed to identify interrelation between photovoltaic
characteristics and features of the recrystalization process in base layers after annealing
in freon as compared with the standard chloride treatment.
Keywords: solar cells FTO/CdS/CdTe, freon, recrystalization.
