A thin film of iodine doped polythiophene was grown photoelectrochemically around the dye-sensitized TiO(2) nanoparticles in a Grätzel 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.
在 Grätzel 电池中，通过光电化学在染料敏化的 TiO(2)纳米粒子周围生长一层掺杂碘的聚噻吩薄膜，并使用 X 射线光电子能谱、电化学阻抗谱和光电压衰减研究了碘掺杂水平对电池性能的影响。在最佳掺杂水平下，与不含聚噻吩的电池相比，该电池的能量转换效率提高了 27.52%。
