Synthesis and photoelectrochemical behavior of nanocrystalline CdS film electrodes

Effect of cooling rate of pre-annealed CdS thin film electrodes prepared by chemical bath deposition: Enhancement of photoelectrochemical characteristics

“…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.…”

“…Metal chalcogenide thin films, such as those of CdS, are one important example of film SC electrodes. Both CBD and Electrochemical Deposition techniques have been widely described to prepare FTO/CdS electrodes for the purpose of photoelectrochemical (PEC) applications [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Investigating the CdS film electrodes from different points of view, such as short-circuit enhancement, open-circuit potential enhancement, SEM surface studies, absorption spectra and photoluminescence (PL) spectra, are known.…”

Enhancement of photoelectrochemical activity of nanocrystalline CdS photoanode by surface modification with TiO2 for hydrogen production and electricity generation

“…CdS powder (0.4 g), acetylacetone (0.02 ml), TX-100(0.01 ml) and deionized H 2 O (4 ml) were ground in an agate mortal into a paste which was applied for the film preparation (Bandaranayake et al, 2003;Jia et al, 2006). The films were dried at 80°C before annealed at 380°C for 30 min in air.…”

Evolution of nanostructure with reaction time for ZnS synthesized by solvothermal process

“…Structural analysis of these as-synthesized ZnS powder samples is carried out by XRD and morphological analyses are carried out by SEM and TEM. We have also investigated the photoluminescence and electrical transport studies of the ZnS nanostructure thin films prepared by doctor blade technique [6]. 1:3] are taken in the teflon-lined chamber, which is then filled with ethylenediamine up to 80% of its volume.…”
