Investigation of DSSCs Performance: The Effect of 1,8-naphthalimid Dyes and Na-doped TiO2
In this paper, we selected three organic dyes based on 1,8-naphthalimide as photosensitizers for DSSCs preparation. The organic dyes were sensitized from acenaphthene as the starting material by standard reactions. Na-doped TiO2 was prepared via one step hydrothermal method for preparation of dye-sensitized solar cells. Spectrophotometric measurements of the organic photosensitizers in DMF and on Na-doped TiO2 substrate were carried out in order to study their maximum absorption wavelength. The maximum absorption wavelength for Dyes 1, 2 and 3 in DMF are 427, 434 and 435 nm and on TiO2 films are 442, 446 and 446 nm, respectively. Finally, the proposed dyes were used as photosensitizer in a dye solar cell structure in the presence of Na-doped TiO2 and their photovoltaic properties were investigated. The conversion efficiencies for the synthesized Dyes 1, 2 and 3 are 1.09%, 1.37% and 1.32%, respectively.
