Abstract The effects of the concentrations of different metal dopants on TiO2 and different metal 1,10-phenanthroline (Phen) complexes on dye sensitized solar cells (DSSCs) yield were investigated. TiO2 were doped with Cu or Mn by different percentages (0.5%, 1%, 2%). Undoped and doped TiO2 nanoparticles were synthesized via microwave assisted hydrothermal method and these nanoparticles were used as photoanode by coating FTO glass by spin coater. Synthesized samples were characterized with SEM, EDS, XRD, DRS. DSSCs were prepared with photoanodes which have doped TiO2 nanoparticles as active layer. These photoanodes were sensitized with Phen. Also for comparing, different metal (Cu, Mn or Cr)-Phen complex dyes were used with undoped TiO2, 1% Cu doped TiO2 and 1% Mn doped TiO2 photoanodes. Prepared solar cells were characterized with linear sweep voltammetry and electrochemical impedance spectroscopy. While N719 sensitized 0.5% and 1% Cu or Mn doped TiO2 have more solar conversion efficiency than 2% doped Cu or Mn and undoped TiO2, all Cu or Mn doped TiO2 photoanodes have more efficiency except 2% doped Mn doped TiO2 than undoped TiO2 photoanode when sensitized with Phen by using interaction of Cu or Mn ions with Phen.

Cu和Mn掺杂量对TiO2性能的影响

摘要 研究了不同金属掺杂剂对TiO2 和不同金属1,10-菲咯啉(Phen) 配合物的浓度对染料敏化太阳能电池(DSSCs) 产率的影响。TiO2 以不同的百分比（0.5%、1%、2%）掺杂有 Cu 或 Mn。通过微波辅助水热法合成了未掺杂和掺杂的 TiO2 纳米粒子，并通过旋涂机涂覆 FTO 玻璃将这些纳米粒子用作光阳极。合成的样品用SEM、EDS、XRD、DRS表征。DSSCs 是用掺杂 TiO2 纳米粒子作为活性层的光阳极制备的。这些光阳极用 Phen 敏化。同样为了比较，不同的金属（Cu、Mn 或 Cr）-Phen 复合染料与未掺杂的 TiO2、1% 的 Cu 掺杂的 TiO2 和 1% 的 Mn 掺杂的 TiO2 光阳极一起使用。制备的太阳能电池用线性扫描伏安法和电化学阻抗谱表征。虽然 N719 敏化的 0.5% 和 1% Cu 或 Mn 掺杂的 TiO2 比 2% 掺杂的 Cu 或 Mn 和未掺杂的 TiO2 具有更高的太阳能转换效率，但所有 Cu 或 Mn 掺杂的 TiO2 光阳极都比未掺杂的 TiO2 光阳极具有更高的效率，除了 2% 掺杂的 Mn 掺杂 TiO2当通过使用 Cu 或 Mn 离子与 Phen 的相互作用用 Phen 敏化时。
