text: " As the electron transport layer of dye-sensitized solar
cells (DSSCs), the photoanode is an important component that affects photoelectric
conversion efficiency (PCE). The commonly used material titanium dioxide (TiO2)
is difficult to prepare as nanostructures with large specific surface area, which
affects dye loading and electrolyte diffusion. Herein, TiO2 nanofibers and ZnO-TiO2
composite nanofibers with different molar ratios are synthesized by electrospinning
technology. The above nanofibers are coated on photoanodes by the doctor blade
method to assemble DSSCs. The influence of the composite ratio of ZnO-TiO2 composite
nanofibers on the photoelectric performance of the assembled DSSCs is explored.
The ZnO-TiO2 composite nanofibers with a molar ratio of 1 : 2 have large specific
surface area and porosity and have the smallest charge transfer resistance at
the photoanode-electrolyte interface. The PCE of the nanofiber-modified DSSCs
reaches a maximum of 3.66%, which is 56% higher than that of the TiO2 nanofiber-modified
DSSCs. The photovoltaic parameters such as open circuit voltage (VOC), current
density (JSC), and fill factor (FF) are 0.58 V, 10.36 mA/cm2, and 0.61, respectively.
Proper compounding of zinc oxide (ZnO) can not only make the nanofibers absorb
more dyes and enhance the light-harvesting ability but also improve the diffusion
of the electrolyte and enhance the electron transport, thus successfully improving
the power conversion efficiency of DSSCs.\r\n "
