Deposition and characterization of screen-printed porous multilayer thick film structures from semiconducting and conducting nanomaterials for use in photovoltaic devices
Three-layer structures of thick (>5 μm) films of nanosized titanium dioxide, zirconium dioxide, and carbon have been screen-printed on a semi-prodn. level for use in photosensitized photovoltaic devices. The films have been characterized using SEM, x-ray diffraction, and nitrogen adsorption/desorption. The rheol. of the screen-printing pastes has been measured and qual. matched to the quality of the resultant film. Three titanium dioxide candidates were evaluated for performance. At low light levels (<300 lx, i.e., typical indoor light levels), photosensitized photovoltaic modules made from these screen-printed structures exhibited equal or superior performance to a com. available amorphous silicon module.
