“…It should be noted that annealing at higher temperature may give negative effect by increasing imperfections and causing unnecessary surface oxidation, thus increasing surface state density. Therefore, the 250 • C was the optimal annealing temperature, which is consistent with literature [1,[26][27][28][29][30].…”

“…Thin film characteristic enhancement by annealing is widely reported in literature [1,5,14,[22][23][24][25][26][27][28][29][30]. Different characteristics of thin films, prepared by different techniques including CBD, such as PL spectra, crystallite size, conductivity, PEC characteristics and others were modified by annealing.…”

“…Some reports dealing with PEC characteristics enhancement of SC thin films, prepared by spray pyrolysis, sputtering or chemical vapor techniques, are available [22,25,[48][49][50][51][52]. Despite the widespread studies on CdS films prepared by CDB [1,5,14,[22][23][24][25][26][27][28][29][30], no earlier comprehensive studies, dealing with effect of cooling rate onto PEC characteristics of such CBD-prepared CdS thin films, were performed. To the best of our knowledge, the effect of cooling rate on both efficiency and stability of such systems under PEC conditions has not been reported.…”

“…22,31 For the three CdS samples doped with different Cu doping concentrations, after the CdCl 2 -annealing, see Fig. 6(b), the V Cd -related defect emission intensity for the 0.1%-Cu-doped sample was much larger than that of the 0.3% and 0.5%-Cu-doped samples.…”

Cu is widely used in the back contact formation of CdTe thin film solar cells. However, Cu is easily to diffuse from the back contact into the CdTe absorber layer and even to the cell junction interface CdS/CdTe. This phenomenon is generally believed to be the main factor affecting the CdTe solar cell stability. In this study Cu was intentionally doped in CdS thin film to study its effect on the microstructural, optical and electrical properties of the CdS material. Upon Cu doping, the VCd− and the surface-state-related photoluminescence emissions were dramatically decreased/quenched. The presence of Cu atom hindered the recrystallization/coalescence of the nano-sized grains in the as-deposited CdS film during the air and the CdCl2 annealing. CdTe thin film solar cell fabricated with Cu-doped CdS window layers demonstrated much decreased fill factor, which was induced by the increased space-charge recombination near the p-n junction and the worsened junction crystalline quality. Temperature dependent current-voltage curve measurement indicated that the doped Cu in the CdS window layer was not stable at both room and higher temperatures.

“…Goto and co-workers [114] used a bath of 2 mM CdSO 4 and 100 mM Na 2 S 2 O 3 at a pH of 2.5 adjusted with H 2 SO 4 to deposit CdS films. They studied the effect of the annealing atmosphere (O 2 , air, or N 2 ) using photoluminescence spectroscopy.…”
