Abstract
A porous CdS:CdO composite structure was formed by screen printing of CdS p owder and sintering in air at high temperature. The X-ray diffraction analy sis of CdS sintered at different temperatures revealed that a CdO formation in the CdS matrix is by the phase transformation of CdS, which may be stat ed as CdS-CdSO4-CdO. The structure, composition and photosensitivity of thi s composite structure depend on the sintering temperature, sintering atmosp here and the flux to semiconductor (FIS) ratio. The results indicate that t he screen printed CdS:CdO structure may be used as a photoconductor in soli d state devices and as a photoelectrode in phsto-electro-chemical energy co nversion systems.
