“…So, ionic liquid, 1, 2-dimethyl-3-propylimidazolium iodide (DMPII), was chosen to dope choline iodide for the formation of plastic crystal electrolytes [35]. According to a recent report [36], a conducting polymer or carbon material can function as a charge transfer mediator using ionic liquids containing iodide anion. We add 10% iodine in DMPII doped choline iodide.…”

“…However, the power conversion efficiencies obtained with ionic liquids at AM 1.5 solar irradiance have been lower than those achieved with organic solvent-based electrolytes (Wang et al, 2003b). DSSC employing the N719 sensitizer and a pure PMII electrolyte without any other additives achieves low efficiencies of 0.6 % at 1 sun (Lee et al, 2010a). DSSC containing PMII with various concentrations of iodine (0.05 to 0.44 M) exhibit efficiencies of 0.7 to 1.7 % at a temperature of 20°C (Berginc et al, 2007).…”

AbstractIn this study, we report improved power conversion efficiencies of various carbon based quasi-solid state electrolytes/DSSCs by optimising the thickness of TiO 2 layer, incorporation of TiO 2 scattering layer and application of dense compact surface layers of TiO 2 on working electrodes. Single wall carbon nanotube (SWCNT) based quasi-solid state electrolytes showed increased power conversion efficiencies from 1.43 % to 3.49 %. For the mixture of graphene and SWCNTs the power conversion efficiencies improved from 2.50 % to 2.93 %.However, graphene based quasi-solid state electrolytes displayed small decreases in power conversion efficiencies from 2.10 % to 1.96 % due to the more viscous nature of this electrolyte. Electrochemical Impedance Spectroscopy (EIS) demonstrated that the addition of these various carbon based nanomaterials into PMII significantly decreases the charge transfer resistance at the counter electrode and hence the much better performance obtained with carbon based quasi-solid state electrolytes compared to pure PMII based DSSCs.

“…Honeycomb-like structures were generated with PVC-g-POEM / TiO 2 hybrid pastes resulting in efficiencies of 7.4% with a polymer-based electrolyte. Secondly, hole transport materials (HTMs) 118 119,120 Finally, the integration of nanocarbons, such as CB, 121,122 SWCNTs as well as MWCNTs, 123,124 and graphene 125 as additives to iodinefree and solid-state electrolytes constitutes a viable strategy to realize ssDSSCs. 21,126 The benefits of implementing nanocarbons into solidstate electrolytes stand out given their significant improvement of the ionic diffusivity, their catalytic activity toward the reduction of the oxidized form of the electrolyte, and the reduction of the internal resistance of the bulk electrolyte.…”

Efforts in the broad field of dye-sensitized solar cells (DSSC) are governed by four key challenges: i) the development of photoelectrodes with high charge injection yields and charge collection efficiencies, ii) the development of low-cost buffer layers, which effectively reduce the back reaction of electrons from the transparent conductive oxide (TCO) to the electrolyte, iii) the design of platinum-free counter electrodes (CE), which feature good electrolyte regeneration yields, and iv) the implementation of (quasi) solid-state and iodine-free electrolytes featuring excellent ionic diffusion and conductivity.
