“…In Figure 7, as in Figure 3, the solid and dotted arrows indicate the onset and termination of illumination, respectively. In contrast to the present study, there was a unique investigation of DSSCs with Q compounded by carbon black or graphite powder [29]; however, it presented only experimental data on the I-V relationship without clarifying the photovoltaic characteristics.…”

“…The above chemical-photovoltaic mechanism can be applied to ordinary DSSCs which are wet-type solar cells with liquid electrolyte and dye without any solid material. However, we can obtain the photovoltaic effect even if we use a conventional rubber sandwiched between the dye and the electrolyte solution, as shown in Figure 7 and in a previous study by Muller [29]. As a liquid, in general, cannot be percolated through a rubber, the creation of the photovoltaics might be due to the electrons and ions transferring over the rubber surface.…”

“…The utilization of rubber is another effective method. However, there have been few studies on the use of rubber, and investigations of silicone rubber (Q) sheets are rare [28,29]. Q in solar cells has been utilized as a substrate of layered materials for photovoltaics, in which case it is not metamorphosed to bring about the photovoltaics [28].…”

Rubber involving magnetic compound fluid (MCF) and TiO2 is effective in dye-sensitized solar cells (DSSCs) to create large efficacy. Wearable and portable solar cells made of MCF rubber are the most desirable as soft materials in robots or flexible devices, and they are further desirable because they have self-generated power and power supply with sensing. Therefore, we investigated the effect of TiO2 catalysts on the photovoltaic effect of MCF rubber DSSCs under large tension and compression. The characteristics of the built-in electricity and photoelectricity were clarified experimentally. The experimental results were explained by a chemical–photovoltaic mechanism involving the behavior of dye, electrolytes, water, and rubber molecules, as well as a catalytic effect of the metal component of the MCF on Ni, Fe3O4, and TiO2. Once we are able to produce solar cells that have large tension and compression, the present experimental results and the model of the chemical–photovoltaic mechanism will be of great interest.

“…Accordingly, among the plethora of works on this topic, one example of a truly innovative and sustainable approach, which is the specific aim of this review, is that recently proposed by the Ehrmann's group. 325 They coated a conductive liquid silicone rubber (Powersil® 466 A/B) layer based on polydimethylsiloxane filled with carbon black and graphite on a viscose cotton woven fabric, which was employed as a CE in lab-scale DSSCs after being sintered at 200°C. Even though the PCE value was found to be rather low (Table 4, entry 5), this work can be effectively considered as the first interesting step toward the development of sustainable textile-based DSSCs.…”

“…[ 16 , 17 , 18 ]. It is worth noting that in recent years, flexible DSSCs assembled on non-planar fibrous conductive substrates with high curvature and excellent stitchability have been constantly developed, which break through the limitations of traditional flat substrates and have the advantages of bendability, light weight and wide application prospects [ 19 , 20 , 21 , 22 ]. As the most important core part of DSSCs, the development of new dyes has always been the mainstream focus of DSSCs research, and people have gradually turned their attention to the study of dye aggregation in recent years.…”

As an important member of third generation solar cell, dye-sensitized solar cells (DSSCs) have the advantages of being low cost, having an easy fabrication process, utilizing rich raw materials and a high-power conversion efficiency (PCE), prompting nearly three decades as a research hotspot. Recently, increasing the photoelectric conversion efficiency of DSSCs has proven troublesome. Sensitizers, as the most important part, are no longer limited to molecular engineering, and the regulation of dye aggregation has become a widely held concern, especially in liquid DSSCs. This review first presents the operational mechanism of liquid and solid-state dye-sensitized solar cells, including the influencing factors of various parameters on device efficiency. Secondly, the mechanism of dye aggregation was explained by molecular exciton theory, and the influence of various factors on dye aggregation was summarized. We focused on a review of several methods for regulating dye aggregation in liquid and solid-state dye-sensitized solar cells, and the advantages and disadvantages of these methods were analyzed. In addition, the important application of quantum computational chemistry in the study of dye aggregation was introduced. Finally, an outlook was proposed that utilizing the advantages of dye aggregation by combining molecular engineering with dye aggregation regulation is a research direction to improve the performance of liquid DSSCs in the future. For solid-state dye-sensitized solar cells (ssDSSCs), the effects of solid electrolytes also need to be taken into account.
