Abstract
A porous CdSe particulate structure was formed by screen printing of high-purity Cd and Se powders with CdCl2 as the flux, followed by sintering at high temperature in air. The structural, morphological, optoelectronic and photoelectrochemical properties of the screen-printed CdSe structure depend on the Cd/Se ratio (composition) and sintering temperature. The final coating consisted of a CdSe:CdO composite structure after sintering in air. This coating exhibited high photosensitivity and large-grain structure, which may be exploited for its use as a photoconductor in solid state devices and as a photoelectrode in photoelectrochemical energy conversion processes.
