“…The device that gain higher R CT value will probably suppress the recombination reaction between the electron and the oxidized Co 3+ ions present in the electrolyte. The correlation between this exchange current density ( J 0 ) and R CT is related by following Buttler–Volmer equation where R CT is the variable and the others are constants; i.e., R is the gas constant, T is 298 K, F is the Faraday constant, and n is the number of electron involved in the redox reaction.…”

The photovoltaic performance of dye-sensitized solar cells fabricated with newly designed and synthesized heterocyclic aromatic pyridine based additive is described. The incorporation of the 4-subsituted pyridine based additive into the quasi-solid state polymer blend of poly(ethylene glycol)–hydroxyethylcellulose (PEG-HEC) with Co2+/3+[bnbip] redox mediator as electrolyte and (E)-3-(5-((E)-2-(1-(5-(2,2-bis(4-(dimethylamino)phenyl)vinyl)thiophen-2-yl)-1H-indol-3-yl)-1-cyanovinyl)thiophen-2-yl)-2-cyanoacrylic acid (DTTCY) as organic photosensitizer has been investigated. The influences of synthesized additives in current–voltage characteristics and photoelectro behavior of devices assembled with [TiO2/DTTCY/Co2+/3+[bnbip]/additive/PEG-HEC/Pt] device were investigated. The presence of different additives in the gel polymer matrix enhanced the photovoltage and was related to the negative shift that occurred in the Quasi Fermi level of TiO2 and also higher charge relaxation time. These additives probably reduce the recombination reaction between the TiO2 surface and the Co3+ ion that boosts the photocurrent (J SC) and PCE of the DSSCs. Furthermore, additives affect the catalytic behavior of the Pt electrode, trap diffusion of the Co3+ species, and charge transfer resistance that limits J sc produced by the device. The PAZ additive possesses an azaindole moiety with bicyclic ring attached on the fourth position of the pyridine, which greatly supports the device for exhibiting good ionic conductivity (1.46 × 10–3 S cm–1), high chemical capacitance (C μ = 11.96 μF), high recombination resistance (9.78 Ω), and lower charge transfer resistance (54.98 Ω) compared with other pyridine based additives. The overall results were also sustained with dielectric constant, dielectric loss, and electrical modulus studies. The cell integrated with PAZ additive generates a maximum J SC of 13.59 mA cm–2 and V oc of 912 mV, yielding an overall power conversion efficiency η of 5.82% under simulated sunlight with 1.5AM condition (i.e., 100 mW cm–2). These QS-DSSCs possess long-term stability for 196 h at ambient conditions.

“…The PGE J59 has a longer electron lifetime value of 43.5 ms, and such high electron recombination resistance of PGE electrolyte redox pairs is responsible for the increased J SC and V OC . Then the reduction in the back reaction of the electron transfer and injected electron from dye attributed with I 3 − to the electrolyte 81 . Such higher resistance values for the gel electrolytes illustrates I 3 − reduction reaction ensues at the counter electrode which may responsible for more power conversion efficiency.…”

Substantially to increase the efficiency of dye‐sensitized solar cells (DSSCs), it has been fabricated with the polymer gel electrolytes (PGEs) by replacing the liquid electrolytes (LEs). Poly (ε‐caprolactone) (PCL) has been synthesized as a crystalline solid biopolymer of about 74% yield using different 6‐membered ring phenolate Al complexes. As prepared PCL was blended with LE used in dye‐sensitized solar cells (DSSCs) to prepare high polydispersity index (PDI) PGE. The prepared PGE shows cross‐linking between carboxyl and hydroxyl groups and interacts with iodide ions to form a chelate complex structure. The PGE was well‐characterized using various analytical tools to demonstrate its structural and surface morphology. The fabricated DSSCs using PGE showed high ionic conductivity (7.76 × 10−4 S cm−1), good tri‐iodide diffusion (2.052 × 10−6 Cm2 S−1), and a highly stable incident photon‐to‐current conversion efficiency (PCE; 5.92%) under solar light illumination (85 mW cm−2). Besides found PGE has improved long‐term stability up to 15 days, and these results proved that the prepared PGE is superior compared to other reported PGEs.

“…The corresponding values again indicate the better performance of LaCeNiO 3 than LaNiO 3 and CeNiO 3 compared with the novel Pt electrode. The higher values of Jsc are attributed to the proportion of dye molecules adsorbed on the TiO 2 surface, the efficiency of electron injection to the FTO and collection by the CE, and the performance of regeneration of the dye 70,71 . The photovoltaic terms such as Jsc follows the order as the LaCeNiO 3 (13.75 mA cm −2 ) > CeNiO 3 (11.12 mAcm −2 ) > LaNiO 3 (8.3 mA cm −2 ) > Pt (3.8 mA cm −2 ).…”

Summary The exorbitant cost, corrosive nature and rare abundance of Pt as counter electrodes has hampered the availability of dye‐sensitized solar cells (DSSCs). Perovskites, the complex metal oxides that have a diverse variety of oxidation states and high oxygen vacancy concentrations, have sparked a lot of interest in energy storage and conversion, with researchers focusing on alternative ideas for rate‐cut counter electrodes to magnify the cost‐cutting of DSSCs. Herein, instead of Pt, the three hydrothermally synthesized perovskites LaCeNiO3, LaNiO3, and CeNiO3 are employed as photocathodes for the fabrication of DSSCs. The electrochemical studies reveal that their electrocatalytic activity towards the iodine/iodide electrolyte is akin to a typical Pt photocathode. The electrons released by the perovskites by oxygen reduction reaction on its surface reduce the I3− to I−, thus the regeneration of the dye to its ground state happens by collecting electrons from the I− ion redox mediator, and finally oxidation of I− to I3− takes place. The LaCeNiO3 shows a higher short circuit current (13.75 mA cm−2) with a power conversion efficiency of 3.46%. It has 579 mV of open‐circuit voltage with a 0.37 fill factor value. The LaNiO3 shows lower values in comparison with LaCeNiO3 because the A‐site cation doping creates lattice deficiencies in LaCeNiO3 making it good for the iodine reduction reaction.
