“…Redox species in the electrolyte transport the holes from the oxidized dye molecules to the counter electrode. In the past decades work has been done to improve the photovoltaic performance of DSSC including optimizing dyecoated nanostructured semiconductor electrodes [5][6][7][8][9], redox couples [10][11][12][13] and electric additives [14,15]. Among them, the addition of electric additives into electrolytes shows high efficiency for enhancing the photovoltaic performance of DSSC.…”

N-cetylpyridinium iodide (N-CPI) as a new electric additive for enhancing photovoltaic performance of the dye-sensitized solar cell (DSSC) was studied. It showed high efficiency for enhancing both the open-circuit voltage and the short-circuit current density of DSSC when the suitable amount of N-CPI as 0.02 M was added in liquid electrolyte. The energy conversion efficiency of DSSC increased from 4.429% to 6.535%, with 47.55% enhancement. Therefore, it is a highly efficient electric additive for DSSC. The intrinsic reason is owing to the special molecular structure of N-CPI, which contains two different polarity groups. As a surfactant, N-CPI could form ordered arrangement in liquid electrolyte, which affects the diffusing ability and the redox reaction of I  /I 3  , and further affects the photovoltaic performance of DSSC.dye-sensitized solar cell, electric additive, photovoltaic performance, N-cetylpyridinium iodide, D app

“…In general, molecular iodine (I 2 ) forms a charge-transfer complex with pyrazole thereby decreasing the problems of sealing and stability to a superior extent, thus acquiescing an efficient performance of the dye sensitized solar cell. The incorporation of pyrazole and I -/I 3 -redox couple into the PMMA/PVDF-based blended solid polymer electrolyte is expected to increase the overall efficiency of the dye-sensitized solar cell in view of the fact that pyrazole (1,2 -diazole) has two nitrogen atoms in the five-membered heterocyclic ring that can each donate lone pair of electrons which may enhance the open circuit photo-voltage (V oc ) of a solar cell as reported earlier by Kusama and Arakawa 9 . In order to characterize the chosen solid polymer electrolyte system and to understand its ion transport behavior, a series of physical techniques including x-ray diffraction (XRD) analysis, complex impedance spectroscopy and I-V measurements have been employed.…”

Thin films of nanocomposite blended solid polymer electrolyte consisting of polymethyl methacrylate (PMMA)/polyvinylidene fluoride (PVDF), potassium iodide (KI) and iodine (I 2 ) as redox couple and pyrazole (PYR) as dopant were prepared using solution casting technique. The consequences of inclusion of PYR within PMMA/PVDF/KI/I 2 were investigated in terms of photovoltaic performance of the cell whereas the PYR impregnated polymer electrolyte solution when introduced into dye-sensitized solar cells (DSSCs) exhibited an overall energy-conversion efficiency of 5.5% at room temperature under AM1.5 illumination.

“…Thiophene ( Table 1, entry 7) when added in 1 M concentration had Li + like effect to enhance the J sc [151]. 4-tBP ( Table 1, entries 8-10) and its derivatives such as methyl pyridine, pyrimidine, pyrazole, triazole, thiazole and quinolone has been extensively explored by Arakawa et al [154,[164][165][166][167]. Out of these, 4-trimethylsilylpyridine ( Table 1, entry 10), have particularly shown better overall performance due to its bulkiness to block recombination reaction at interface, and better electron donating ability without negatively effecting the electron injection [157].…”

During the last two and half decade modifying anatase TiO 2 has appreciably enhanced our understanding and application of this semiconducting, non-toxic material. In the domain of DSCs, the main focus has been to achieve band adjustment to facilitate electron injection from anchored dyes, and high electronic mobility for photo-generated electron collection. In retrospection, there is a dire need to assimilate and summarize the findings of these studies to further catalyze the research, better understanding and comparison of the structure-property relationships in modifying TiO 2 efficiently for crucial photocatalytic, electrochemical and nanostructured applications. This chapter aims at categorizing the typical approaches used to modify TiO 2 in the domain of DSCs such as through TiO 2 paste additives, TiO 2 doping, metal oxides inclusion, dye solution co-adsorbing additives, post staining surface treatment additives and electrolyte additives. A summary of the consequences of these modifications on electron injection, charge extraction, electronic mobility, conduction band shift and surface states has been presented. This chapter is expected to hugely benefit the researchers employing TiO 2 in energy, catalysis and battery applications.
