We have investigated the sensitization of screen-printed and spray-painted titanium dioxide coatings by chemically deposited cadmium selenide thin films. The structural, optical and photoelectrochemical characterization of the composite films indicate the strong role played by the titanium dioxide morphology during the sensitization step and during photovoltaic conversion. Air annealing at temperatures close to 400 degreesC helps to improve the photocurrent quantum yields and the photostability of the composite coatings in broad pH media. The spectral response, I-V curves and photostability of the sensitized spray-painted and screen-printed TiO2 coatings is superior in polysulfide media than in ferro/ferricyanide electrolytes, indicating the possibility of electroless etching and/or surface modification by ferricyanide. Overall, the sensitized films based on spray-painted TiO2 show stronger photocurrents under visible light and withstand better the deleterious effect of the ferro/ferricyanide media.
