“…Above 10% the deposition rate decreases, the reduction being very steep for those films deposited in presence of pure oxygen. These results agree pretty well with the literature 2,5 . The deposition rate decrease is probably due to the reaction between tellurium and/or cadmium molecules and oxygen molecules, during their transport to the substrate.…”

“…In principle, this reaction could favor oxides formation. The role of the oxygen on the properties of CdTe films has been widely investigated 2,5 . It is known that the presence of oxygen in the films improves the cell efficiency.…”

“…In CSS technique, the source and substrate temperatures, the system pressure and the oxygen partial pressure are the most important deposition parameters, deeply affecting the physical and microstructural properties of the film. Several works have been published about the effect of these parameters [2][3][4] . For example, some authors 5 report that a small amount of oxygen during the growth of the film plays a very important role in the layer of CdTe, contributing for increasing p-type conductivity and decreasing resistivity.…”

Influence of deposition parameters on the properties of CdTe films deposited by close spaced sublimation

CdTe thin films are used as absorber layer in CdS/CdTe solar cells. The microstructure of this absorber layer plays a fundamental role in photovoltaic conversion and can be controlled by the deposition parameters used during the film growth. In this work, CdTe thin films were deposited by the CSS method onto glass substrates previously covered with In 2 O 3 :Sn. The effects of pressure, source temperature and substrate temperature on the microstructural properties of the films were studied. The properties were mainly influenced by the pressure, the presence of oxygen in the reaction chamber, and the substrate temperature. For films deposited under an argon atmosphere, an increase in grain size and a reduction of the texture were observed as the pressure and substrate temperature were increased. The introduction of oxygen in the atmosphere led to a decrease in the deposition rate and affected the microstructure and composition of the film. Films deposited under an argon-oxygen atmosphere have smaller grains than those deposited under argon and are richer in Te. The addition of oxygen to the atmosphere apparently did not result in the formation of oxides.

“…Some authors have already observed the same effect in cadmium telluride thin films. They showed that a small amount of oxygen in the gaseous atmosphere reduced the deposition rate by half of the initial value [12]. In spite of this, it is generally agreed that oxygen plays an important role in the production of efficient devices [6,12].…”

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.
