“…Nonetheless, factors affecting D and are almost acting in different directions. Typically, the stability of indigo dyes (here Dye1) is higher than of thioindigo dyes (here Dye2) [21]. As a result, it is expected to yield larger D values when the mixture is mostly containing Dye1, which is in full agreement with our observations.…”

“…Although the importance of of DSSCs has been noticed by the researchers and engineers alike, a few reported on durability (D) of such devices, in spite of its vital importance from an application point of view. Takada et al [21] and Lin et al [22] noticed some points to improve D of DSSCs. Accordingly, it was found that utilization of carbon as working electrode or Pt as counter electrode improves the D of DSSCs.…”

A novel methodology was implemented in the present study to concurrently control power conversion efficiency () and durability (D) of co-sensitized dye solar cells. Applying response surface methodology (RSM) and Desirability Function (DF), the main influential assembling (dye volume ratio and anti-aggregation agent concentration) and operational (performance temperature) parameters were systematically changed to probe their main and interactive effects on the and D responses. Individual optimization based on RSM elucidated that D can be solely controlled by changing the ratio of vat-based organic photosensitizers, whereas takes both effects of dye volume ratio and anti-aggregation concentration into account. Among the studied factors, the performance temperature played the most vital role in and D regulation. In particular, however, multi-objective optimization by DF explored the degree to which one should be careful about manipulation of assembling and operational parameters in the way maximization of performance of a co-sensitized dye solar cell.

“…Thus, it is critical to find new materials, which are well-appointed for replacing Pt that possesses good electroconductivity and electrocatalytic activity (ECA) toward the reduction of tri-iodide ions and cost-effective [1,3]. Recently, researchers are interested in the utilization of Pt-free materials such as conducting polymers (CPs) [4], carbon materials [5], and transition metals based inorganic materials [6] as new CE materials in DSSCs due to their remarkable properties that can enhance the efficiency of the solar cell [7]. Poly(3,4-ethylenedioxythiophene) (PEDOT) is a conducting polymer suitable to be utilized as a CE due to its good stability, high electrochemical activity, and excellent transparency [8][9][10].…”

PEDOT-based material counter electrodes (CEs) are recently given an enormous attention as new renewable energy sources due to their cost-effectiveness and accessibility, coupled with the simplicity of production. The existing dye-sensitized solar cells (DSSCs) are expensive because they are made using platinum-based glass electrode. In this work, a new CE, that is, poly(3,4-ethylenedioxythiophene)-graphene oxide/titanium dioxide (PEDOT-GO/TiO 2 ) with a low charge transfer resistance ( ct = 9.0 Ω), was fabricated. In addition, PEDOT-GO/TiO 2 CE possesses a good electrocatalytic activity (ECA) toward the tri-iodide ions reduction and an improved efficiency of 1.166% was reached in DSSC.

Counter electrodes (CEs) of dye-sensitized solar cells (DSCs) are usually fabricated by depositing catalytic materials on substrates. The poor adhesion of the catalytic material to the substrate often results in the exfoliation of catalytic materials, and then the deterioration of cell performance or even the failure of DSCs. In this study, a highly adhesive surface layer is in situ grown on the titanium foil via a facile process and applied as CEs for DSCs. The DSCs applying such CEs demonstrate decent power conversion efficiencies, 6.26% and 4.37% for rigid and flexible devices, respectively. The adhesion of the surface layer to the metal substrate is so strong that the photovoltaic performance of the devices is well retained even after the CEs are bended for 20 cycles and torn twice with adhesive tape. The results reported here indicate that the in situ growth of highly adhesive surface layers on metal substrate is a promising way to prepare durable CEs for efficient DSCs.
