“…The electrolyte film was sandwiched between two stainless steel electrodes with surface area 2cm x 2cm, under spring pressure. The ionic conductivity, σ of the electrolyte was calculated using equation: (1) where t is the thickness of the electrolyte film and A is the electrolyte-electrode contact area. The bulk resistance, Rb is determined from the Nyquist plot.…”

Effect of Temperature on the Transport Property of PVdF-HFP-MPII-PC/DME Gel Polymer ElectrolytesAbstract. Gel polymer electrolytes employing the co-polymer poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) as the polymer host were prepared by soaking the PVdF-HFP films in a liquid electrolyte of 1.0M 1-methyl-3-propyl imidazolium iodide (MPII) ionic liquid dissolved in a mixture of propylene carbonate (PC) and 1,2-dimetoxyethane (DME) (v/v=7:3). Conductivity of PVdF-HFP-MPII-PC/DME electrolyte was investigated as a function of temperature. Conductivity enhancement with temperature is attributed to the increase in the number, n and mobility, μ of free ions. The n and μ of free ions have been determined quantitatively by impedance spectroscopy.

“…An appropriate HTM in solid-state dye-sensitized solar cells (SSDSCs) must satisfy several requirements: (i) the upper edge of the valence band of the p-type semiconductors must be located above the highest occupied molecular orbital (HOMO) ground state level of the dye; (ii) its hole mobility should be sufficiently high; (iii) it must be able to fill pores of mesoporous n-SC; (iv) it should be transparent in the range of dye absorption mostly, e.g., the visible light; and (iv) it should be stable during operation [13,[37][38][39][40][41]. Copper-based inorganic semiconducting hole transport materials, such as CuI, CuSCN, CuO and Cu 2 O, have shown promises for their use in dye-sensitized and quantum dot-sensitized solar cells.…”

Considering the increasing global demand for energy and the harmful ecological impact of conventional energy sources, it is obvious that development of clean and renewable energy is a necessity. Since the Sun is our only external energy source, harnessing its energy, which is clean, non-hazardous and infinite, satisfies the main objectives of all alternative energy strategies. With attractive features, i.e., good performance, low-cost potential, simple processibility, a wide range of applications from portable power generation to power-windows, photoelectrochemical solar cells like dye-sensitized solar cells (DSCs) represent one of the promising methods for future large-scale power production directly from sunlight. While the sensitization of n-type semiconductors (n-SC) has been intensively studied, the use of p-type semiconductor (p-SC), e.g., the sensitization of wide bandgap p-SC and hole transport materials with p-SC have also been attracting great attention. Recently, it has been proved that the p-type inorganic semiconductor as a charge selective material or a charge transport material in organometallic lead halide perovskite solar cells (PSCs) shows a significant impact on solar cell performance. Therefore the study of p-type semiconductors is important to rationally design efficient DSCs and PSCs. In this review, recent published works on p-type DSCs and PSCs incorporated with an inorganic p-type semiconductor and our perspectives on this topic are discussed.

“…[3] Strategies have also been developed to improve the stability of the systems including the use of additives and, most important, the use of non-aqueous solvents. [4] On the other hand, the number of cases is certainly less where ruthenium dyes are used in dye-sensitized photoelectrochemical cells (DSPECs) for performing the demanding water oxidation reaction. [5] The two most widely used dyes are the simple [Ru(bpy)3] 2+ (bpy = 2,2'-bipyridine) and its phosphonated derivative, [Ru(4,4'-PO3H2-bpy)(bpy)2] 2+ .…”

Abstract:The complex [Ru(bpy)2L] 2+ , where bpy = 2,2'-bipyridine, L = 4-(phenylethynyl)-2,2'-bipyridine, was prepared in its racemic and resolved forms (and . The phenylethynyl unit on the bipyridine for the complex acts as a binding site for -cyclodextrin in water (1:1 complex, K = 3390 M -1 ) or -cyclodextrin (2:1 complex, K1 = 887 M -1 , K2 = 8070 M -1 ). The presence of the cyclodextrin provides partial protection to the complex under light-activated water oxidation conditions.
