Investigation of Photovoltaic Properties of Dye-Sensitized Solar Cells Based on Mixture of Indoline Dyes

This research describes a double layered dye sensitized solar cells by using organic dyes based on indoline. Spectrophotometric evaluations of the mixtures of dyes in solution and on a TiO2 substrate were carried out in order to assess changes in the status of the dyes. Additionally, electrochemical properties of each mixture of dyes were investigated. Oxidation potential measurements for all of mixture ensure a thermodynamically favorable charge transfer to the TiO2 conduction band. Finally, dye sensitized solar cells are fabricated in order to determine the photovoltaic behaviour and conversion efficiencies of each mixture.
