“…In comparison, the solar conversion efficiency of the 1D TiO 2 hybrid solid-state electrolyte was the highest achieved in this research (6.1%); this correlates with the highest Jsc of 14.6 mA cm −2 , a Voc of 0.65 V, and a FF of 0.64. It should be noted that the efficiency of the mesoporous carbon-based DSSCs using the 1D TiO 2 hybrid solid-state electrolyte represents one of the highest values reported for Pt-free counterelectrode-based DSSCs to date, as shown in Table S2 [ 36 , 37 , 38 , 39 , 40 ]. Moreover, the carbon-based DSSCs fabricated with commercial TiO 2 hybrid solid-state electrolyte show efficiency of 4.8% with a Jsc , Voc, and FF of 12.7 mA cm −2 , 0.63 V, and 0.60, respectively.…”

One-dimensional (1D) titanium dioxide (TiO2) is prepared by hydrothermal method and incorporated as nanofiller into a hybrid polymer matrix of polyethylene glycol (PEG) and employed as a solid-electrolyte in dye-sensitized solar cells (DSSCs). Mesoporous carbon electrocatalyst with a high surface area is obtained by the carbonization of the PVDC-g-POEM double comb copolymer. The 1D TiO2 nanofiller is found to increase the photoelectrochemical performance. As a result, for the mesoporous carbon-based DSSCs, 1D TiO2 hybrid solid-state electrolyte yielded the highest efficiencies, with 6.1% under 1 sun illumination, in comparison with the efficiencies of 3.9% for quasi solid-state electrolyte and 4.8% for commercial TiO2 hybrid solid-state electrolyte, respectively. The excellent photovoltaic performance is attributed to the improved ion diffusion, scattering effect, effective path for redox couple transfer, and sufficient penetration of 1D TiO2 hybrid solid-state electrolyte into the electrode, which results in improved light-harvesting, enhanced electron transport, decreased charge recombination, and decreased resistance at the electrode/electrolyte interface.

“…The cationic quasi-gel electrolyte showed a higher electrolyte holding capability, elasticity and higher conductivity while the anionic one showed higher PCE. They were succeeded in achieving a high power conversion efficiency of 6.30% [ 39 ]. Furthermore, Jiao et al studied the cyclic voltametric behavior of polyaniline by growing a thin film of PANI on a plastic substrate.…”

Polymers in High-Efficiency Solar Cells: The Latest Reports

Third-generation solar cells, including dye-sensitized solar cells, bulk-heterojunction solar cells, and perovskite solar cells, are being intensively researched to obtain high efficiencies in converting solar energy into electricity. However, it is also important to note their stability over time and the devices’ thermal or operating temperature range. Today’s widely used polymeric materials are also used at various stages of the preparation of the complete device—it is worth mentioning that in dye-sensitized solar cells, suitable polymers can be used as flexible substrates counter-electrodes, gel electrolytes, and even dyes. In the case of bulk-heterojunction solar cells, they are used primarily as donor materials; however, there are reports in the literature of their use as acceptors. In perovskite devices, they are used as additives to improve the morphology of the perovskite, mainly as hole transport materials and also as additives to electron transport layers. Polymers, thanks to their numerous advantages, such as the possibility of practically any modification of their chemical structure and thus their physical and chemical properties, are increasingly used in devices that convert solar radiation into electrical energy, which is presented in this paper.

“…Performances of such a nanocomposite heavily depend on the hybrid interfaces between the [Ru(bpy) 3 ] 2+ core and the TiO 2 substrate to ensure long-term stability of the dye and efficient energy transfer and charge transport. Notably, under irradiation of colloidal solution, after electron injection, the lateral hole hopping process between the transient [Ru(bpy) 3 ] 3+ species and the adjacent [Ru(bpy) 3 ] 2+ cores at the surface of the TiO 2 NPs influences the kinetics of the charge recombination, which is accelerated for a well-packed system. , Some examples on mesoporous thin film proved that modification of TiO 2 with a conducting polymer contributed for better dye adsorption, charge transport, and long-term stability, , while the presence of an organic or inorganic interlayer at the interface reduces the charge recombination process. ,, Recently, the lateral substitution of a Ru(II) polypyridyl core anchored on TiO 2 with long alkyl chains has shown a decrease in the desorption process upon prolonged light irradiation . The improvement in stability is attributed to an increase in the hydrophobicity of the surface that retains the dye.…”

Herein we report the synthesis and electrochemical and photophysical behaviors of a nanocomposite TiO 2 /P-[Rupyr] 2+ , where [Ru(bpy) 3 ] 2+ (bpy = 2,2′-bipyridine) cores bearing two pyrrole substituents on distinct bipyridines and a phosphonic anchoring group on the third bipyridine are immobilized on TiO 2 colloidal nanoparticles. Under visible light and in the presence of O 2 as a sacrificial electron scavenger, TiO 2 /P-[Ru-pyr] 2+ was converted into a suprastructure TiO 2 /P-oligo(Ru-pyr), where the [Ru(bpy) 3 ] 2+ cores were linked together through a pyrrole coupling reaction. The photoinduced charge separated state (e − )TiO 2 / Ru II -pyr + was revealed by electron paramagnetic resonance (EPR) spectroscopy ((e − )TiO 2 signal). The oxidative coupling of pyrroles was ascertained by identifying the additional organic radical EPR signal with DFT calculations of pyrrole-derived oligomers, combined with X-ray photoelectron spectroscopy (XPS) results. TiO 2 /P-oligo(Ru-pyr) exhibited a higher rate of electron injection from [Ru(bpy) 3 ] 2+ * to TiO 2 than for colloidal nanoparticules without pyrrole denoted as TiO 2 /P-[Ru] 2+ . The composites were then electrophoretically deposited on a fluorine-doped tin oxide surface and tested as photoanodes. At a bias of 0.12 V vs Ag/Ag + 0.01 M, FTO/TiO 2 /P-oligo(Ru-pyr) in the presence of tertiary amine as a sacrificial electron donor, displayed a current density double that of FTO/TiO 2 /P-[Ru] 2+ under similar conditions. XPS confirmed the stability of [Ru(bpy) 3 ] 2+ cores after the photopolymerization process, but a partial desorption was observed after the electrophoretic deposition.
