Recent progress in electrospinning TiO₂ nanostructured photo‐anode of dye‐sensitized solar cells

Abstract

The key to improving the performance of dye-sensitized solar cells is the photo-anode that has much dye adsorption and short optoelectronic transmission path. Electrospun TiO 2 films in photo-anode have high specific surface area and meet the demand exactly. The article summarizes these efforts in TiO 2 photo-anode improvement, including various morphology, different onedimensional and two-dimensional composite structure, and varied element doped TiO 2 photo-anode. Besides, the review makes comparison with these different TiO 2 photo-anodes in photoelectric properties. The conclusions provide a clear guidance in design of morphology, structure, and doping, which is helpful for researcher to improve the performance of the anode and increase the photoelectric conversion efficiency especially those prepared using electrospinning.

Electrospinning Nanoparticles-Based Materials Interfaces for Sensor Applications

“…The amorphous structure and more oxygen vacancy defects make TiO 2 /C nanofibers-based devices lose photosensitivity, causing the linear response of semiconductor nanosensors to pH changes, which further confirms the practical application of the fabricated device as a pH sensor, Figure 10c. The development of semiconductor nanosensors provides a new route for the development of other functional nanosensors [127].…”

Application of carbon dots in dye‐sensitized solar cells: A review

“…This process can also be described as holes entering the hole transport layer. Finally, electrons migrate through the external load to complete the circuit . Generally, the energy of the conduction band of the absorber layer is higher than the electron transport layer, while the valence band energy level of the absorber layer is lower than the hole transport layer, thereby driving the transition of electrons and holes.…”

Effect of Eu3+ - dopant concentration on structural and luminescence properties of SrY2O4 nanocrystalline phosphor and potential application in dye-sensitized solar cells

“…Phosphors doped with rare earth ions give rise to strong emissions and plays important role in modern display technology, such as plasma display panel (PDP), white light emitting diodes (WLEDs), field emission display (FED) and in industry lighting, such as tricolor lamps and solar cells [3][4][5][6][7]. On the other hand, dye-sensitized solar cells (DSSCs) attracted a lot of attention due to the low fabrication cost and high efficiency [8][9][10]. The biggest challenge in DSSCs is chemical stability as well as conversion efficiency.…”
