Abstract

In this work, the efficiency of dye-sensitized solar cells (DSSC) was improved by capping TiO₂ with simple aromatic amines as a complexing agent. The aromatic amines, aniline and o-phenylenediamine capped TiO₂ composites were synthesized via hydrothermal route and used as scattering layer in dye-sensitized solar cell (DSSC). Markedly, the maximum photo-conversion efficiency of 9.84% was achieved with o-phenylenediamine capped-TiO₂ composite as o-phenylenediamine capped-TiO₂ showed higher reflectivity than the pristine TiO₂, which is highly beneficial for reflecting the photons back to photoanode. In addition, the average life time of carriers in o-phenylenediamine capped-TiO₂ was found to be 9.8 ms, which was 2 times higher than the pristine TiO₂ (4.29 ms).
