“…310 It has been observed that the morphology of CEs also plays an important role in determining the electrocatalytic activity of DSSC devices, where CEs with large surface area nanostructures tend to show larger PCE values and a higher electrocatalytic activity of the DSSCs. 282 The DSSCs with TiS 2 /graphene hybrids 199 and TiS 2 /PEDOT:PSS composites 200 336 showed a 28% increase in PCE than that of pure TiO 2 photoanode.…”

Dye-sensitized solar cells (DSSCs) are gaining considerable interest as alternatives to semiconductor-based thin film solar cells. The noble metal platinum (Pt) is conventionally used as a counter electrode (CE) material for fabricating DSSCs, since Pt is expensive and scarce, therefore, new materials have been explored to develop cost-effective Pt-free counter electrodes. Two-dimensional (2D) graphene-based counter electrodes have achieved the highest power conversion efficiency (PCE, h) of 13%, which has stimulated research activities in 2D layered transition metal dichalcogenides (TMDs) for developing Pt-free DSSCs.In this review, progress made on alternative counter electrodes for fabricating low-cost Pt-free DSSCs, based on earth-abundant 2D TMDs including MoS

“…Indeed, tellurides were first used in solar cells as photoanodes to capture sunlight, and they allowed significant improvement of PCEs. [137][138][139][140] However, around the year 2013 the first telluride-based CEs were designed by Guo et al [141] They synthesized CoTe and NiTe 2 nanostructures using a composite-hydroxide-mediated (CHM) approach and applied them as CEs for DSSCs. As expected, these Reproduced with permission.…”

“…To solve this problem, the structure and connection of ZnO should be investigated. For example, Wan et al [6] introduced Bi 2 Te 3 nanosheets (NSs) as a composite photoelectrode to achieve an enhanced DSSC performance. The composite photoelectrode was prepared by mixing Bi 2 Te 3 NSs and ZnO NPs.…”

The purpose of this study is to synthesize ZnO aggregate films using simple precipitation with polymer modification for linkage improvement of the ZnO photoelectrode. The starting materials of zinc acetate solution and ammonia solution were mixed under violent stirring conditions. A portion of the polymer (polyethylene glycol) was slowly added into the mixed solution to obtain the viscous ZnO precursor. The precursor was then coated onto a fluorine-doped tin oxide substrate and annealed to form ZnO films. The scanning electron microscopy results revealed the formation of ZnO aggregates with flower-like microstructures. The appearance of Zn and O elements indicated a fair ZnO formation. The X-ray diffraction patterns and Raman shift confirmed the hexagonal wurtzite crystal structure of the ZnO aggregates. For dye-sensitized solar cell (DSSC) application, power conversion efficiency was enhanced because of the improved photovoltaic characteristics including the open-circuit voltage, fill factor, series resistance, shunt resistances and recombination resistance, perhaps, due to the large particle size of the ZnO aggregates and their flower-like microstructures. The flower-like microstructure likely acts as a bridge to link each ZnO particle. The flower-like microstructure plays the role of an express pathway in electron transport in the DSSC. Therefore, the ZnO aggregation with a flower-like microstructure has the potential to improve the electron transport for efficiency enhancement of a DSSC.
