Charge Transport In Zirconium Doped Anatase Nanowires Dye-Sensitized Solar Cells: Trade-Off Between Lattice Strain and Photovoltaic Parameters

Zirconium (Zr) is doped up to 5 at. % in anatase TiO2 nanowires by electrospinning and used as working electrode in dye-sensitized solar cells. Variations observed in the photovoltaic parameters were correlated by electrochemical impedance spectroscopy, open circuit voltage decay, and X-ray diffract...
