Effect of coadsorbent properties on the photovoltaic performance of dye-sensitized solar cells.
نویسندگان
چکیده
Stearic acid as a coadsorbent, which has a low dipole moment and high solubility, retarded the rate of dye adsorption during the competitive anchoring process on the TiO(2) layer in dye-sensitized solar cells (DSCs), thereby increasing the content of strongly bound dye on the TiO(2) surface. This resulted in an approximately 25% improvement in both J(SC) and the power conversion efficiency of the DSCs, even for much lower dye coverage.

In this paper we selected two metal-free dyes (Dye 1 and Dye 2) based on 1,8-naphthalimide. The proposed dyes were sensitized from acenaphthene as the starting material by standard reactions. Spectrophotometric measurements of the organic dyes in DMF and on TiO2 substrate were carried out in order to assess changes in the status of the dyes. Maximum absorption wavelengths for Dye...

متن کاملApplication of azo dye as sensitizer in dye-sensitized solar cells
An azo dye used as photosensitizers in Dye-sensitized solar cells DSSCs. Azo dyes economically superior to organometallic dyes because they are color variation and cheap. The spectrophotometric evaluation of an azo dye in solution and on a TiO2 substrate show that the dye form J-aggregation on the nanostructured TiO2 substrate. Oxidation potential measurements for used azo dyes ensured an energ...

A commercial Ti-Nanoxide was deposited on In-doped SnO2 (ITO) polymer substrates by tape casting technique with different thicknesses (7, 14 and 36μm) to be used as photoelectrode in flexible dye-sensitized solar cells (DSSCs). Ruthenium dye was adsorbed on each TiO2 film for 24 h. The resulting photoelectrodes were used to form flexible DSSCs in combination with...
