TiO ₂ /TiO ₂ nanofibers (NF) and FePt/TiO ₂ nanofibers (NF) were successfully prepared by the sol-gel method and electrospinning technology. Nanofibers were added to the photoanode of the dye-sensitized solar cell (DSSC) as an additional layer, and its effect on the DSSC characteristics were studied. FePt/TiO ₂ nanofibers were determined using an X-ray diffractometer (XRD), confirming that the FePt nanoparticles were successfully doped into the TiO ₂ nanofibers. Electrochemical impedance spectroscopy (EIS), J-V characterization and incidental photon to current efficiency (IPCE) measurements showed how the FePt/TiO ₂ nanofibers improved the DSSC photovoltaic characteristics. The photoanode modified with FePt/TiO ₂ showed improved photoelectric conversion efficiency (η). Compared with unmodified DSSCs (TiO ₂ only photoanode), the η improved by 16%. Following this research, FePt/TiO ₂ nanofibers appear to be a key candidate for improving DSSC in photovoltaic performance.

FePt/TiO2 纳米纤维修饰光阳极染料敏化太阳能电池的制备及表征


采用溶胶-凝胶法和静电纺丝技术成功制备了TiO ₂ /TiO ₂纳米纤维(NF)和FePt/TiO ₂纳米纤维(NF)。将纳米纤维作为附加层添加到染料敏化太阳能电池（DSSC）的光电阳极，并研究了其对 DSSC 特性的影响。使用X射线衍射仪(XRD)对FePt/TiO ₂纳米纤维进行测定，证实FePt纳米颗粒成功掺杂到TiO ₂纳米纤维中。电化学阻抗谱 (EIS)、JV 表征和偶然光子电流效率 (IPCE) 测量表明 FePt/TiO ₂纳米纤维如何改善 DSSC 光伏特性。用FePt/TiO ₂修饰的光电阳极表现出更高的光电转换效率(η)。与未修饰的 DSSC（仅 TiO ₂光阳极）相比，η 提高了 16%。根据这项研究，FePt/TiO ₂纳米纤维似乎是提高 DSSC 光伏性能的关键候选材料。
