We present simple methods of paste preparation and appropriate processing of thick films. Methodology - Active layers of photoconductive cells based on doped CdS0.32Se0.68 were prepared by screen-printing and sintering at 530 oC. A sulfide - selenide mixture or a mixed crystal material and propylene glycol was deposited as a paste. Propylene glycol served as the temporary paste binder. Cadmium chloride was used as a fluxing agent and a donor source. Copper(II) chloride was used as an acceptor source. The effect of the paste composition and sintering time on the resistance and slope of the resistance vs. illumination dependence of cells was investigated. These parameters were checked again after 8 years of cell storage. Workplace J.
