“…The CdS thin films deposited by CBD can fulfill these requirements. So the thickness of CdS has much importance for the high efficiency of solar cell [15][16][17]. CdS (CBD) thin films are grown by Cadmium Chloride, Ammonium Nitrate, and Potassium Hydroxide after heating to a specific temperature Thiourea added to start the fabrication process [18][19][20].…”

Abstract. Thin films of Cadmium Sulfide (CdS) are deposited on microscope glass slides by two techniques, chemical bath deposition (CBD) and close spaced sublimation (CSS). Cadmium Sulfide thin films fabricated by both procedures are characterized by spectrophotometer, scanning electron microscopy (SEM) and X-ray diffraction (XRD). Optical analysis of CdS thin films shows changes in transmittance, refractive Index and energy band gap by using two different techniques. XRD and SEM results show CdS thin film samples with better crystalline structure for close spaced sublimation technique and grain size is also found different for these two methods. CdS thin films fabricated by any of these two methods are good window layers with small thickness and suitable for CdTe/CdS/ITO based solar cells.

“…Besides being thin, this film must also be continuous, to prevent short circuit in the cell. The chemical bath deposition (CBD) of CdS films can meet these requirements very well [3][4][5][6]. CBD-CdS films are grown by decomposition of thiourea (the source of S) in an alkaline solution, in the presence of Cd 2+ ions.…”

“…CBD-CdS films are grown by decomposition of thiourea (the source of S) in an alkaline solution, in the presence of Cd 2+ ions. The advantages of this technique are the low cost of the process and the presence of oxygen in the solution, which is naturally incorporated into the film, improving the device performance [6]. A technological concern is the disposal of the large quantity of residues resulting from the process.…”

“…A technological concern is the disposal of the large quantity of residues resulting from the process. CdS thin films have also been grown by the close spaced sublimation (CSS) technique [6][7][8]. CSS-CdS films are grown in low vacuum regime, by sublimating a CdS source separated from the substrate by very small distances, usually few millimeters.…”

Microstructural and optical properties of CSS and CBD-CdS thin films for photovoltaic solar cells

et al. 2014

This work compares the properties of CdS films deposited by CBD and CSS techniques. The influence of the deposition parameters on the properties of the films was investigated. The thickness of CBD films ranged from 80 to 100nm and was affected by the concentration of reactants in the solution. For CSS films, the thickness was controlled in the 100-300nm range, being strongly influenced by the source/substrate temperatures and pressure. Grain size in CSS films was larger than in CBD films. Transmittance of CBD and CSS films ranged from 80 to 90%, but the band gap in CSS films was narrower than in CBD films, which means that CSS films transmit less of the blue part of the solar spectrum than CBD films. However, the growth of CdS films by CSS technique may be advantageous because the CdS/CdTe device could be fully manufactured in the same system.

“…Many methods have been employed to deposit thin TiO 2 films. Among these are the Ti(OiPr) 4 hydrolysis sol-gel method, followed by 500 -600 ºC calcination, chemical vapor deposition (CVD), physical vapor deposition (PVD), chemical bath deposition (CBD), reactive cathode pulverization and atomic layer deposition (ALD) [12][13][14] . Chemical vapor deposition assisted by plasma (PECVD) has also been used to grow TiO 2 films on a great variety of substrates 15 .…”
