Nanofiber membranes are starting to be used as an electrolyte storage medium because of their high porosity, which causes ionic conductivity, producing high energy. The ability of nanofiber membranes to absorb electrolytes proves their stability when used for a long time. In this study, the loading of acetylene carbon black (ACB) on polyacrylonitrile (PAN) is made by the electrospun method, which in turn is applied as an electrolyte medium in DSSC. Materials characterization was carried out through FTIR to determine the functional groups formed and SEM to observe morphology and diameter distribution. Furthermore, for DSSC performance, efficiency and EIS tests were carried out. The optimum nanofiber membrane was shown by esPACB1, with the highest efficiency reaching 1.92% with a porosity of 73.43%, nanofiber diameter of 172.9 ± 2.2 nm, an absorbance of 1850, and an electron lifetime of 0.003 ms.
纳米纤维膜因其高孔隙率开始被用作电解质存储介质，高孔隙率导致离子传导性，产生高能量。纳米纤维膜吸收电解质的能力证明了其在长期使用时的稳定性。在本研究中，通过电纺丝法将乙炔炭黑（ACB）负载在聚丙烯腈（PAN）上，进而将其用作染料敏化太阳能电池（DSSC）中的电解质介质。通过傅里叶变换红外光谱（FTIR）进行材料表征以确定形成的官能团，并通过扫描电子显微镜（SEM）观察形态和直径分布。此外对于DSSC性能，进行了效率和电化学阻抗谱（EIS）测试。esPACB1显示出最佳的纳米纤维膜，最高效率达到1.92%，孔隙率为73.43%，纳米纤维直径为172.9±2.2nm，吸光度为1850，电子寿命为0.
