摘要:In this paper we studied preparation of working films of dye-sensitized solar cells using screen printed method. The organic dye based on phenoltiazine with cyanoacrylic acid as the electron donor group utilized as photosensitizer. Fluorine-doped thin oxide FTO coated glass is transparent electrically conductive and ideal for use in dye-sensitized solar cells. FTO glass was coated by screen printed method and investigated the effect of fabrication´s parameters. The influence of the squeegee printing angle of 37°, 55° and 65° on the dye-sensitized solar cells performance was investigated in order to assess changes in the status of the power conversion efficiency. The Conversion efficiency for 37°, 55° and 65° are 2.71 and 1.96 and 1.58, respectively. When using the FTO glass for working electrode preparation, a low squeegee angle gives a porous thick film, which is ideal for dye absorption.
