Al and Mg doped TiO2-ZrO2 semiconducting nanopowder samples were prepared for dye sensitized solar cell application. The structural properties were examined by X-ray diffraction. The results revealed that TiO2 exists in two different phases Anatase and Rutile whereas ZrO2 exists in Monoclinic and Tetragonal phases. The average crystallite size for Al and Mg doped samples was found to be 8.16 nm and 6.90 nm respectively. The optical properties were evaluated by UV-Visible spectroscopy. Both the Al and Mg doped TiO2-ZrO2 nanocomposites show optical absorption in UV region. The optical bandgap was found to be 2.96 eV and 3.34 eV for Al and Mg doped TiO2-ZrO2 nanocomposites respectively. Dye-sensitized solar cell was fabricated using Al and Mg doped TiO2-ZrO2 nanocomposite as conducting material and pomegranate juice as sensitizer. The I-V characteristics were recorded to measure photo response of DSSC. Photovoltaic parameters like open circuit voltage, power conversion efficiency, and fill factor were evaluated for the fabricated solar cell. The power conversion efficiency of DSSC fabricated with Al and Mg doped TiO2-ZrO2 nanocomposites was found to be 3.88% and 2.15% respectively.

Abstract


Al and Mg doped TiO2-ZrO2 semiconducting nanopowder samples were prepared for dye sensitized solar cell application. The structural properties were examined by X-ray diffraction. The results revealed that TiO2 exists in two different phases Anatase and Rutile whereas ZrO2 exists in Monoclinic and Tetragonal phases. The average crystallite size for Al and Mg doped samples was found to be 8.16 nm and 6.90 nm respectively. The optical properties were evaluated by UV-Visible spectroscopy. Both the Al and Mg doped TiO2-ZrO2 nanocomposites show optical absorption in UV region. The optical bandgap was found to be 2.96 eV and 3.34 eV for Al and Mg doped TiO2-ZrO2 nanocomposites respectively. Dye-sensitized solar cell was fabricated using Al and Mg doped TiO2-ZrO2 nanocomposite as conducting material and pomegranate juice as sensitizer. The I-V characteristics were recorded to measure photo response of DSSC. Photovoltaic parameters like open circuit voltage, power conversion efficiency, and fill factor were evaluated for the fabricated solar cell. The power conversion efficiency of DSSC fabricated with Al and Mg doped TiO2-ZrO2 nanocomposites was found to be 3.88% and 2.15% respectively.
