[en] Changes in microstructure and texture during annealing of polycrystalline cadmium selenide films have been investigated. The effects of annealing atmosphere and substrate material on the temperature interval, kinetics and texture of recrystallization have been established. The temperature of recrystallization initiation in cadmium selenide films on glass substrate precoated with SnO₂ decreases from 550 deg C for non-alloyed to 300 deg C for chlorine-alloyed layers and to 350 deg C for the layers alloyed with chlorine and copper. It is supposed that ease of recrystallization in the case of alloying is connected with the effect of alloy additions on vacancy concentrations in the material
