Dye-sensitized solar cells (DSSCs) based on natural sensitizers have become a topic of significant research because of their urgency and importance in the energy conversion field and the following advantages: ease of fabrication, low-cost solar cell, and usage of nontoxic materials. In this study, the chlorophyll extracted from papaya leaves was used as a natural sensitizer. Dye molecules were adsorbed by TiO2 nanoparticle surfaces when submerged in the dye solution for 24 h. The concentration of the dye solution influences both the amount of dye loading and the DSSC performance. The amount of adsorbed dye molecules by TiO2 nanoparticle was calculated using a desorption method. As the concentration of dye solution was increased, the dye loading capacity and power conversion efficiency increased. Above 90 mM dye solution concentration, however, the DSSC efficiency decreased because dye precipitated on the TiO2 nanostructure. These characteristics of DSSCs were analyzed under the irradiation of 100 mW/cm2. The best performance of DSSCs was obtained at 90 mM dye solution, with the values of Voc, Jsc, FF, and efficiency of DSSCs being 0.561 V, 0.402 mA/cm2, 41.65%, and 0.094%, respectively.

“…Seeking more plentiful and affordable resources, however, reinstate Pt is a major research eld for DSSCs. To response to these chalanges, substitute of low-cost and productive components of metal oxides, chalcogenides, polymers and carbon based materials are suggested by the researchers [6][7][8][9][10][11].…”

In this report, for the rst time synthesized FeNi 2 S 4 /rGO composite as Pt free counter electrode (CE) by facile hydrothermal method without employing template or surfactant. Complete investigations of phase evolutions by XRD patterns and TEM indicate that spinel structure with nanosheets and nanospherical morphologies. The individual spherical shaped nanoparticles (30-35 nm) of FeNi 2 S 4 were exploited on the 2D ultrathin rGO nanosheets surface. This is useful for the provision of further electrolyte adsorptions and responsive electrocatalytic sites. The DSSC constructed with FeNi 2 S 4 /rGO hybrid composite CE showed a conversion e ciency of 9.98%, better than that by FeNi 2 S 4 CE (4.87%) and also commercial Pt (6.21%). The outstanding e ciency of the FeNi 2 S 4 /rGO hybrid composite CE even better than commercial Pt is effective alternative to Pt CE in the DSSCs.

“…Further optimization and improvement of each component of the cell are thus required to achieve the desired efficiency. A large amount of effort has been put into the evaluation of hole-transporting materials, photoanodes, dye molecules, and other stable photoactive layers of solar cells [ 8 , 9 , 10 , 11 , 12 ]. The performance of a device depends on the material development and fabrication methodology, as well as cell design.…”

“…During recombination, the dye absorbs photons and excite electrons to a higher state, which is denoted as (D*/Lowest unoccupied molecular orbital (LUMO)) ( Figure 2 b). A wide-bandgap semiconductor, such as TiO 2 , is used as a photoanode to evoke photoelectric effects [ 11 , 17 ]. After excitation, electrons from the highest occupied molecular orbital (HOMO) of dye molecules adsorbed on the surface of the photoanode are injected into the conduction band of the photoanode material.…”

Synergetic Effects of Hybrid Carbon Nanostructured Counter Electrodes for Dye-Sensitized Solar Cells: A Review

This article provides an overview of the structural and physicochemical properties of stable carbon-based nanomaterials and their applications as counter electrodes (CEs) in dye-sensitized solar cells (DSSCs). The research community has long sought to harvest highly efficient third-generation DSSCs by developing carbon-based CEs, which are among the most important components of DSSCs. Since the initial introduction of DSSCs, Pt-based electrodes have been commonly used as CEs owing to their high-electrocatalytic activities, thus, accelerating the redox couple at the electrode/electrolyte interface to complete the circuit. However, Pt-based electrodes have several limitations due to their cost, abundance, complicated facility, and low corrosion resistance in a liquid electrolyte, which further restricts the large-area applications of DSSCs. Although carbon-based nanostructures showed the best potential to replace Pt-CE of DSSC, several new properties and characteristics of carbon-CE have been reported for future enhancements in this field. In this review, we discuss the detailed synthesis, properties, and performances of various carbonaceous materials proposed for DSSC-CE. These nano-carbon materials include carbon nanoparticles, activated carbon, carbon nanofibers, carbon nanotube, two-dimensional graphene, and hybrid carbon material composites. Among the CE materials currently available, carbon-carbon hybridized electrodes show the best performance efficiency (up to 10.05%) with a high fill factor (83%). Indeed, up to 8.23% improvements in cell efficiency may be achieved by a carbon-metal hybrid material under sun condition. This review then provides guidance on how to choose appropriate carbon nanomaterials to improve the performance of CEs used in DSSCs.
