The impact of photoanode preparation on the photovoltaic performance of dye-sensitized solar cells was investigated. The effects of titanium dioxide layer thickness, type of solvent and immersion time used for photoanode fabrication, and addition of coadsorbents and a cosensitizer on photon-to-current conversion efficiency and photovoltaic parameters were studied. Commercially available N719 and dyes prepared in our research group, 5,5′-bis(2-cyano-1-acrylic acid)-2,2′-bithiophene and 2-cyano-3-(2,2′:5′,2″-terthiophen-5-yl)acrylic acid, were applied as sensitizers. The effect of studied factors on UV–vis properties and morphology, that is, the root-mean-square roughness of the photoanode, was examined and correlated with the photovoltaic response of the constructed devices. Additionally, the amount of dye molecules adsorbed to the TiO2 was investigated. It was found that all considered factors significantly impacted photovoltaic parameters. Also, the photoanode stability was tested by measuring photovoltaic parameters after 14 months.

“…Photoanode should possesses good electrical property such as high electronic conductivity to accept electrons from lowest unoccupied molecular orbitals (LUMO) of dye molecules. The most common material for photoanode of DSSC is TiO2 since this material is cheap, non-toxic, has good electrical property and high stability due to wide bad gap that is 3.2 eV at room temperature [1]. TiO2 can be prepared in film form on conducting substrates such as indium tin oxdie (ITO) and fluorine tin oxide (FTO) via various techniques such as screen printing [2], spray pyrolysis [3], liquid phase deposition [4], electrophoretic deposition [5], microwave [hydrothermal [6], electrochemical anodization [7] and doctor blade [8].…”
