Abstract

The effect of the pulsed - laser annealing on the parameters of CdS thin layers in the medium of oxygen was studied. The CdS thin layers were deposited by spray pyrolysis and surface treatment by nanosecond pulses of XeCl - laser. The changes in the layers were characterized by SEM, XRD and XPS. The results showed that a change in the morphology of the surface occurred; a by-surface layer consisted of CdO with high transparency and conductivity is formed in consequence of oxidation of CdS. These results are discussed in the context of window layers in solar cells.
