Influence of synthesized thiourea derivatives as a prolific additive with tris(1,10-phenanthroline)cobalt(II/III)bis/tris(hexafluorophosphate)/ hydroxypropyl cellulose gel polymer electrolytes on dye-sensitized solar cells

Poly(ethylene glycol)–poly(propylene glycol)–poly(ethylene glycol) and polyvinylidene fluoride blend doped with oxydianiline-based thiourea derivatives as a novel and modest gel electrolyte system for dye-sensitized solar cell applications

“…52 In 2019, our group reported a PCE of 9.1% for gel polymer electrolyte prepared using hydroxypropyl cellulose with symmetric thiourea derivatives of tetramethylbenzidine with Co(II/III)phen redox couple. 48 From the above-mentioned literature, we can conclude that using heteroatom-rich aromatic compounds with distinctive polymers for GPEs can help to obtain stable and efficient dye-sensitized solar cell devices.…”

“…The thiourea additives were synthesized using a previously reported procedure. 48 The general scheme is depicted in Fig. 1.…”

“…42 Most remarkably, the latest reports describe the use of urea as an additive in GPE to improve the efficiency of DSSCs. 45,46,48,51,52 In 2007, Wu et al used PEG (polyethylene glycol) (40%) and propylene carbonate (60%) with iodide salts to achieve an efficiency of 7.22%. 53 PEG-based polymers play a major role due to their enhanced segmental motion of the ions in the electrolyte.…”

Poly(3,4‐ethylenedioxythiophene) in Dye‐Sensitized Solar Cells: Toward Solid‐State and Platinum‐Free Photovoltaics

“…[92][93][94] In the standard device configuration, the electrolyte consists of a redox shuttle dissolved in an organic solvent along with additives conceived to boost photocurrent and voltage of the DSSC. [95,96] Overall, the electrolyte takes care of oxidized dye regeneration, a milestone step to make these solar cells regenerative, and guarantees an efficient charge transfer between the electrodes. [70] Last, but not least, electrolyte components should be designed to be easily upscaled at a large scale in terms of processability, abundancy and end-of-life disposal.…”

An Interaction of Chloro Substituted Alkoxy Thiourea as Dopant in Carboxymethyl Cellulose (CMC) for Solid Polymer Electrolyte

“…Nowadays, thiourea derivatives have been used widely in numerous advanced materials application such as in drug development for pharmaceutical application, 1 chemical sensors for anions and gas detection, 2,3 active layer for photovoltaic solar cells and catalysis in promoting the crosscoupling reaction. 4,5 The uniqueness of thiourea derivatives incorporating with varies functional group substitutions make them versatile compounds to be applied in advanced materials application. The presence of diprotic donor group insight thiourea derivatives plays a significant role in providing enough electron to the conjugated system of thiourea derivatives, in which, the π-conjugated system of thiourea derivatives make it as a promising candidate for molecular wires.…”
