文摘

A thin film of iodine doped polythiophene was grown photoelectrochemically around the dye-sensitized TiO₂ nanoparticles in a Gr盲tzel cell, and the effect of iodine doping level on the cell performance was investigated using X-ray photoelectron spectroscopy, electrochemical impedance spectroscopy, and photovoltage decay. At an optimum doping level, the cell demonstrated the enhanced energy conversion efficiency by 27.52% compared to the cell without polythiophene.
