“…The electrochemical impedance spectroscopy (EIS) is a very useful techniq understand the electron injection and recombination processes in DSSCs Electrochemical impedance spectroscopy (EIS) was used to further evaluate the imp interfacial charge transfer processes in a DSSC. Generally, there are three semi showed in the EIS spectrum, which correspond to electron recombination resis (Rrec) at the interfaces of photoanode/dye/electrolyte, charge-transfer resistance photoanode/dye/electrolyte interface (RCT), and Warburg diffusion process of elect (Zw), as typically reported for other DSSC devices [41][42][43]. The electroche impedance spectra (EIS) of DSSCs were obtained under a forward bias of −0.70 V dark to elucidate correlation of VOC with those dyes, and the Nyquist plots for D based on DP-1 to DP-3 are shown in Figure 7.…”

A series of novel double-anchoring dyes for phenoxazine-based organic dyes with two 2-cyanoacetic acid acceptors/anchors, and the inclusion of a 2-ethylhexyl chain at the nitrogen atom of the phenoxazine that is connected with furan, thiophene, and 3-hexylthiophene as a linker, are used as sensitizers for dye-sensitized solar cells. The double-anchoring dye exhibits strong electronic coupling with TiO2, provided that there is an efficient charge injection rate. The result showed that the power conversion efficiency of DP-2 with thiophene linker-based cell reached 3.80% higher than that of DP-1 with furan linker (η = 1.53%) under standard illumination. The photovoltaic properties are further tuned by co-adsorption strategy, which improved power conversion efficiencies slightly. Further molecular theoretical computation and electrochemical impedance spectroscopy analysis of the dyes provide further insight into the molecular geometry and the impact of the different π-conjugated spacers on the photophysical and photovoltaic performance.

“…Recently, dye-sensitized solar cells (DSSCs) and perovskite solar cells belong to the often investigated so-called third-generation photovoltaic cells which can be described as electrochemical solar cells. This is why diverse review papers are available, giving a good overview of DSSCs [ 302 , 303 , 304 , 305 , 306 ] as well as perovskite solar cells [ 307 , 308 , 309 , 310 , 311 ]. Nevertheless, research on other electrochemical solar cells and specialized devices is still going on.…”

Electrochemical devices convert chemical reactions into electrical energy or, vice versa, electricity into a chemical reaction. While batteries, fuel cells, supercapacitors, solar cells, and sensors belong to the galvanic cells based on the first reaction, electrolytic cells are based on the reversed process and used to decompose chemical compounds by electrolysis. Especially fuel cells, using an electrochemical reaction of hydrogen with an oxidizing agent to produce electricity, and electrolytic cells, e.g., used to split water into hydrogen and oxygen, are of high interest in the ongoing search for production and storage of renewable energies. This review sheds light on recent developments in the area of electrospun electrochemical devices, new materials, techniques, and applications. Starting with a brief introduction into electrospinning, recent research dealing with electrolytic cells, batteries, fuel cells, supercapacitors, electrochemical solar cells, and electrochemical sensors is presented. The paper concentrates on the advantages of electrospun nanofiber mats for these applications which are mostly based on their high specific surface area and the possibility to tailor morphology and material properties during the spinning and post-treatment processes. It is shown that several research areas dealing with electrospun parts of electrochemical devices have already reached a broad state-of-the-art, while other research areas have large space for future investigations.

“…7 I À /I 3 is generally considered as the electrolyte in DSSCs. 8 There are reports that the minor changes in the donor-spacer-anchoring group can change the photophysical and electrochemical properties of the dye molecules. 9 Hence, the design of molecular sensitizers depends on the appropriate selection of donor and anchoring groups for achieving more efficient solar cells.…”
