Abstract :
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 acceptor group was utilized as photosensitizer. Fluorine-doped thin oxide (FTO) coated glass is transparent and electrically conductive which is ideal for use in dye-sensitized solar cells. FTO glass was coated by screen printed method for investigating the effect of fabrication 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° were 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.
