“…The details about the formation of oriented thinfilm CdS by PLD have been published in previous articles. 5,6 The photocurrent and transmission spectra measured with polarized light reflect the dichroism of the films by shifting the onset of the interband absorption of CdS Ќ 55 meV below that of CdS ʈ . 7 The single-photon photoluminescence ͑SPL͒ excited with the continuous wave 325 nm line of a He-Cd laser, however, does not reflect the dichroism of the films and shows an opposite shift in energy.…”

The photoluminescence of oriented thin-film CdS on glass formed by laser deposition was investigated employing 200 fs, 1.54 eV laser pulses at room temperature. The ultrafast excitation caused a two-photon absorption process, which results in purely green emission at the band gap. The spectra are fitted very well by the application of the van Roosbroeck–Shockley relation, density of states, and Urbach’s rule demonstrating the intrinsic character of the radiative recombination. It is further shown that the energy position of the emission peak depends on the polarization of the impinging laser beam due to the dichroism of the highly oriented films.

“…However, the work of Cheon and Zink [13] showed that the ZnS and CdS thin films photodeposited on a quartz substrate had preferential growth along the c-axis which is in good agreement with the present work. The orientation dependence on the laser flux was investigated by Ullrich et al [14].…”

The effects of white light illumination during the deposition of CdS thin films in a quasi-closed volume on the structural, photoelectrical and optical properties are investigated. The films were highly c-axis oriented with an increasing intensity of (002) reflection as the illumination increases. The room temperature resistivity values of the CdS films decreased in the range of 107-104 Ω cm. The photosensitivity in the fundamental absorption region and the transparency in the transmission region considerably increased as the illumination increased. Under 100 mW cm-2 insolation, the efficiencies of the CdS/CdTe solar cells based on CdS window materials which were deposited: (1) in the dark; and (2) under an illumination of 150 mW cm-2; were found to be 1.8% and 7.3%, respectively.

“…In the pulsed laser deposition technique, film properties depend on some deposition parameters including laser wavelength, pulse duration, energy intensity, background gas and system geometry [14]. In addition to the above parameters the annealing temperature of target is also important.…”
