“…Thus, we have achieved high open circuit voltage in the ZnO-based device, and the observed high V OC is also comparable with other reported devices and represented in Fig. S6 † 51–57 . The fast electron transport in the TiO 2 /ZnO photoanode is the reason for the high J SC and V OC as compared with the TiO 2 photoanode.…”

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.

The rapid depletion of fossil fuel soon would drive us to look for an alternative clean energy resources to meet the global energy demand. Several attempts have been made in recent years to improve the performances of renewable energy devices to achieve higher efficiency and to compete with conventional energy sources. Solar cells have great potential for a sustainable solution to the world energy crisis. The titania (TiO 2 ) is the most frequently used photoanode in dye-sensitized solar cells (DSSC) but its interfacial defects and restricted optical features lead it to low performance. The advent of Au/ TiO 2 nanocomposite materials as photoanode in DSSC has explored new approaches in the successful optimization of renewable energy devices. The newly invented plasmonic dyesensitized solar cells (PDSSC) also have optimized performance as well as reduced adverse effects. The fabrication of nanostructured composites with the inclusion of metallic nanoparticles is very helpful to increase the light scattering by plasmonic effects. The PDSSC facilitates the electronic transport by reducing the electron-hole recombination rates due to the surface plasmon resonance effect of gold nanoparticles anchored with titania that's why these types of cells achieved maximum attention in the current era. In this review, fundamentals, recent developments, and future perspectives of PDSSC have been discussed.
