Abstract

We present the results obtained by photomodulation (PM) at room temperature of semiconductor CdS thin films grown in large area (450 cm ²). The thin films were deposited on conducting glass (SnO ₂:F 7 Ω/□) by radio frequency-planar magnetron sputtering with a substrate temperature (T_s) of 250 °C, an Argon pressure of 20 mTorr, a radio frequency power of 300 W and with a deposition time (t _d) of 60 min. A thermal treatment with CdCl₂ in these thin films at different annealing times was carried out. In general the PM spectra show a better crystal quality in the CdS thin films annealed with CdCl₂, which is corroborated with atomic force microscopy (AFM) and observed in the efficiency of the solar cells processed with these films.
