“…The counter-electrode is a platinum (Pt) layer screen printed through a precursor on FTO-coated substrate and then fired at 480 °C for 30 min 41 . The latter procedure, borrowed from DSSC technology 42 , converts the used Pt precursor paste into catalytic Pt nanometre-sized islands that permit a facile exchange of electrons/ions at the electrode/electrolyte interface maintaining a high degree of transparency with a resulting transmittance of up to 79% between 400 and 700 nm 43 (Supplementary Fig. S1 ).…”

In recent years, organic electronic materials have been shown to be a promising tool, even transplanted in vivo, for transducing light stimuli to non-functioning retinas. Here we developed a bio-hybrid optoelectronic device consisting of patterned organic polymer semiconductors interfaced with an electrolyte solution in a closed sandwich architecture in order to study the photo-response of photosensitive semiconducting layers or patterns in an environment imitating biological extracellular fluids. We demonstrate an artificial retina model composed of on an array of 42,100 pixels made of three different conjugated polymers via inkjet printing with 110 pixels/mm2 packing density. Photo-sensing through three-colour pixelation allows to resolve incoming light spectrally and spatially. The compact colour sensitive optoelectronic device represents an easy-to-handle photosensitive platform for the study of the photo response of artificial retina systems.

“…The overall electrocatalytic ability of CEs was characterized using these parameters. A larger I pc denotes greater electrocatalytic ability, and a smaller Δ E p indicates a lower overpotential toward the catalytic reduction of the triiodide ion to the iodide ion in DSSCs [ 10 , 25 ]. Compared with 30 s Pt CE as shown in Figure 5 , 0.05 C PProDOT-Bz 2 /30 s Pt CE exhibits a higher I pc than that of 30 s Pt CE.…”

“…In recent years, polyaniline (PANI) [ 12 , 13 ], polypyrrole (PPy) [ 14 ], poly(3,4-ethylenedioxythiophene) (PEDOT) [ 15 , 16 , 17 , 18 ], poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) [ 19 , 20 , 21 ], polythiophene (PTh) [ 10 ], and poly(3,3-diethyl-3,4-dihydro-2 H -thieno-[3,4- b ][1,4]-dioxepine) (PProDOT-Et 2 ) [ 21 , 22 ] have been reported as potential CEs of DSSCs. Moreover, DSSCs using CP-based electrolytes have many benefits associated with solvent-free devices such as improved long-term stability, high thermal stability, low liquid leakage, and so forth [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. However, the applications of poly(3,3-dibenzyl-3,4-dihydro-2 H -thieno[3,4- b ][1,4]dioxepine) (PProDOT-Bz 2 ) in CE of DSSCs are not reported so far.…”

In this study, poly(3,3-dibenzyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine)/platinum composite films (PProDOT-Bz2/Pt) were used as counter electrodes (CEs) in dye-sensitized solar cells (DSSCs). The composite films were prepared on fluorine-doped tin oxide (FTO) glass by radio frequency (RF) sputtering to deposit platinum (Pt) for 30 s. Afterwards, PProDOT-Bz2 was deposited on the Pt–FTO glass via electrochemical polymerization. The electron transfer process of DSSCs was investigated using electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The DSSCs with 0.05 C/cm2 PProDOT-Bz2-Pt composite films showed an open circuit voltage (Voc) of 0.70 V, a short-circuit current density (Jsc) of 7.27 mA/cm2, and a fill factor (F.F.) of 68.74%. This corresponded to a photovoltaic conversion efficiency (η) of 3.50% under a light intensity of 100 mW/cm2.

“…Furthermore, alternative catalyst materials than Pt can also be chosen, such as low temperature carbon composites [72,73,74], carbon nanotubes [49,75,76,77], graphene flakes [78,79,80,81], or conducting polymers, such as PEDOT:TsO and PEDOT:PSS [75,82,83].…”

Dye-sensitized solar cells (DSSCs) have been intensely researched for more than two decades. Electrolyte formulations are one of the bottlenecks to their successful commercialization, since these result in trade-offs between the photovoltaic performance and long-term performance stability. The corrosive nature of the redox shuttles in the electrolytes is an additional limitation for industrial-scale production of DSSCs, especially with low cost metallic electrodes. Numerous electrolyte formulations have been developed and tested in various DSSC configurations to address the aforementioned challenges. Here, we comprehensively review the progress on the development and application of electrolytes for DSSCs. We particularly focus on the improvements that have been made in different types of electrolytes, which result in enhanced photovoltaic performance and long-term device stability of DSSCs. Several recently introduced electrolyte materials are reviewed, and the role of electrolytes in different DSSC device designs is critically assessed. To sum up, we provide an overview of recent trends in research on electrolytes for DSSCs and highlight the advantages and limitations of recently reported novel electrolyte compositions for producing low-cost and industrially scalable solar cell technology.
