A dye-sensitized and flexible TiO2 fiber with multilayer structure was prepared by using brush method as the photoanode in the efficient flexible fibrous dye-sensitized solar cells (FFDSSCs) to avoid electronic recombination and improve the electronic capture efficiency. The composite Pt counter electrode, preparation from the surface modification of the electrodeposited Pt wire by using a simple one-step thermal decomposition approach of H2PtCl6 isopropanol and n-butyl alcohol (volume ratio = 1:1) solution, provided a significant improvement in electrocatalytic activity, which was confirmed by extensive electrochemical tests. The FFDSSC assembled with the fiber-shaped TiO2 photoanode and the composite Pt counter electrode achieves an enhanced photoelectric conversion efficiency of 6.35%, higher than that of the FFDSSC with monolayer fibrous TiO2 photoanode and electrodeposited Pt wire counter electrode. More importantly, the photoelectric conversion efficiency of 6.35% is comparable to that of the FFDSSC based on the pure Pt wire counter electrode (6.32%). The FFDSSC with high elasticity, flexibility, and stretchability can adapt to complex mechanical deformations, which is of great significance for the development of wearable electronics in the future.

“…To overcome these issues, J. Yue et al, modified the working photoanode tin oxide (SnO 2 ) compact layer by europium ion doped ytterbium fluoride (Eu 3 + : YbF 3 ) and fabricated long term stable DSCs (Figure 12(b)) for the first time in the year 2017. [105] These devices revealed enhanced PCE when compared to the cells without compact layer is related to the high transparency of the compact layer, reduction in the electrons recombination rate and enhanced UV light harvesting and the corresponding IPCE spectrum is shown in Figure 12(a) [106] Recently in 2018, J. Llonas demonstrated improved light harvesting ability with the incorporation of Eu 3 + doped Y 2 WO 6 /TiO 2 layer as working electrode in DSC devices.These DSC devices with DC layer exhibited better photovoltaic performance of efficiency 3.9 % relative to bare TiO 2 (3.1 %).

“…It is obvious from the reported literature [155] that UV degradation effects can be mitigated by DC/UC phosphor-based devices that increases the light harvesting ability.With the utilization of DC/UC compact layer the device exhibits a longer electron lifetime, demonstrating that a better interface contact between TiO 2 film and FTO and a reduced back reaction transfer of electrons with I 3 , causing in a higher V OC relative to bare devices.Besides these advantages, the electrons get transported more rapidly to FTO substrate than directly to FTO substrate, larger recombination probability that results in existing of more electrons in the CB of semiconductor and high electron diffusion coefficient that facilitates more photogenerated electrons into the photoanode. Hence these RE based UC/DC phosphor layer protects the dyes against degradation [105] due to conversion of UV light into visible light before irradiation on dye.…”

Although the efficiency of Dye‐sensitized and Perovskite solar cell is still below the performance level of market dominance silicon solar cells, in last few years they have grabbed significant attention because of their fabrication ease using low‐cost materials, and henceforth these cells are considered as a promising alternative to commercial photovoltaic devices. However, third generation solar cells have significant absorption in the visible region of solar spectrum, which confines their power conversion efficiency. Subsequently, the performance of current photovoltaics is significantly hampered by the transmission loss of sub‐band‐gap photons. To overcome these issues, rare earth doped luminescent materials is the favorable route followed to convert these transmitted sub‐band‐gap photons into above‐band‐gap light, where solar cells typically have significant light‐scattering effects. Moreover, the rare earth based down/up conversion material facilitates the improvement in sensitization, light‐scattering and device stability of these devices. This review provides insight into the application of various down/up conversion materials for Dye‐sensitized and perovskite solar cell applications. Additionally, the paper discusses the techniques to improve the photovoltaic performance in terms of current density and photo voltage in detail.

“…As is well known, the fluorescent materials are able to absorb the short-wavelength photons and convert them into longwavelength photons with better spectral responsiveness for solar cells [11][12][13]. Proceeding from this angle, rare-earth europium complexes can be introduced into solar cells with a significant impact on the photoelectric conversion efficiency [14][15][16][17]. Consequently, the optical conversion materials are capable of absorbing UV radiation effectively, which are worthy of further research and development.…”

Intense reddish-orange fluorescence of Eu3+ is observed in multiligand europium complexes Eu(BA)(TTA)2 and Eu(BA)(TTA)2Phen doped polyvinylpyrrolidone (PVP). Under 367 nm UVA-LED pumping with 708.5 μW, the net emission powers are as high as 204.8 and 243.2 μW, and the total emission photon numbers are derived to be 635.9 × 1012 and 754.9 × 1012 cps for Eu(BA)(TTA)2 and Eu(BA)(TTA)2Phen doped PVP thin films, respectively. It is incredible that the quantum yield (QY) is up to 57.87% in the former; furthermore, as the introduction of Phen, the QY of Eu3+ is increased to 62.03%, verifying the effectiveness of multiligands in photon conversion. Conclusive photon quantification and efficient fluorescence emission reveal the potential of europium complexes/PVP as UV-visible conversion layers for enhanced solar cells.
