Abstract

This study aims to enhance photovoltaic performance of dye-sensitized solar cells (DSSCs) by modification of photoanode with nanofibers (NFs) as an additional layer. g-C3N4 and ZnS (CN-ZnS) were selected for the modification of TiO2 nanofibers. The g-C3N4 was synthesized using a calcination method, while the CN-ZnS was successfully prepared through a simple hydrothermal method. Subsequently, CN-ZnS/TiO2 NFs with different mixing ratios were fabricated using electrospinning technology. The synthesized material was characterized by X-ray diffraction and scanning electron microscopy. The positive impact of incorporating the additional layer on the photovoltaic performance of DSSCs was confirmed through electrochemical impedance spectroscopy, UV-vis spectroscopy, J-V characterization, and incident photon-to-current efficiency measurements. Notably, the DSSC modified with 1% CN-ZnS/TiO2 NFs achieves an efficiency of 5.44%, and it reaches an efficiency of 7.04% under low illumination (30 mW/cm2). These results suggest that CN-ZnS/TiO2 NFs are promising for enhancing the performance of DSSCs.

静电纺丝制备g- c3n4 - zns掺杂TiO2纳米纤维及其在染料敏化太阳能电池中的应用

本研究旨在通过纳米纤维（NFs）作为附加层修饰光阳极来提高染料敏化太阳能电池（DSSCs）的光伏性能。选择g-C3N4和ZnS （CN-ZnS）对TiO2纳米纤维进行改性。g-C3N4采用烧结法合成，CN-ZnS采用简单的水热法制备。随后，采用静电纺丝技术制备了不同配比的CN-ZnS/TiO2 NFs。用x射线衍射和扫描电镜对合成材料进行了表征。通过电化学阻抗谱、紫外-可见光谱、J-V表征和入射光子电流效率测量，证实了添加额外层对DSSCs光伏性能的积极影响。值得注意的是，1% CN-ZnS/TiO2 NFs修饰的DSSC效率为5.44%，在低照度（30 mW/cm2）下效率为7.04%。这些结果表明，CN-ZnS/TiO2纳米颗粒有望提高DSSCs的性能。
