Abstract
In dark conditions as well in light , the behaviour of CdS films sprayed under the same conditions varies with the atmosphere used during the process of pyrAolys,ls . The study of the current-voltage ( J-E ) characteristics , drawn from a CdS / (Sx-2/S-2) liquid schottky barrier reveals some changes in the potential value related to the onset dark-current . Analysis of the film's photoresponse shows that a specific behaviour of the photocurrent Jp parameter plotted against E is obtained with each the pyrolyzed samples. The film composition and its surface texture appear to provide the most likely explanation for this phenomenon . Regenerative cell made of CdS photoanode is highly efficient with N2 -treated samples . The lower power conversion corresponds to films pyrolyzed in He atmosphere . The use of H2 as described in this paper , leads to an interfacial instability
