Abstract:
In the present study, an organic dye based on benzoxanthene-3,4-carboxilic anhydride was synthesized to be used in dye-sensitized solar cell.In order to do that, acenaphthene was utilized as the main reagent and a series of consecutive reactions were conducted to yield the mentioned benxoxanthene-3,4-carboxilic anhydride, including bromination, nitration, oxidation, reduction, phenolation and cyclization. In order to purify the intermediates and the final dye, recrystallization was done and followed by column chromatography and the materials were analyzed by Fourier Transform Infrared Spectroscopy, Nuclear Magnetic Resonance Spectroscopy, UV-Vis Spectrophotometery and Mass Spectroscopy. Finally, the synthesized dye was used as a sensitizer in a dye-sensitized solar cell. Photovoltaic parameters of the fabricated dye-sensitized solar cell were investigated by solar simulator and were compared to the cell fabricated by the dye N719 as a reference. Results show that the ratio of the power conversion efficiency of the cell based on the benzoxanthene-3,4-carboxilic anhydride to the corresponding value of the cell based on N719 was approximately 34%.
