Solid electrolytes based on {1 − (x + y)}ZrO 2 -(x)MgO-(y)CaO ternary system: Preparation, characterization, ionic conductivity, and dielectric properties

“…6 represents the Arrhenius plots of oxygen ion conductivities for pure and doped samples. Ionic conductivity of samples is expressed by an Arrhenius equation as${\mathrm{\sigma }}_{\mathrm{T}}={\mathrm{\sigma }}_0\times \exp \left(\frac{-\mathrm{italicEa}}{\mathrm{italickT}}\right)$where σ T is the total conductivity, the pre-exponential factor is σ 0, activation energy is denoted by Ea, and k is the Boltzmann constant [31]. At lower temperature, pure ZrO 2 was not a good oxide ion conductor; for conductivity enhancement anionic vacancies are promoted by doping [32].…”

Significant Enhancement in Optoelectronic Properties of γ-CuxAg1–xI Films Induced by Highly (111)-Preferred Orientation and Cu Content at Room Temperature

“…3−5 Moreover, γ-CuI and γ-AgI stable at room temperature can form a continuous solid solution copper silver iodide (Cu x Ag 1−x I) with varying components and a tunable band gap. 6,7 Investigations on the surface photovoltage (SPV) and transient SPV (TSPV) have been demonstrated to be critical for understanding carrier dynamics including carrier separation and carrier recombination behaviors for improving the efficiency of photovoltaic devices. 8 To improve efficiency and performance of the devices, it has been found that enhancing the photocurrent, photovoltage, and stability is a promising approach.…”

“…To date, optoelectronic materials applied in photovoltaic devices have attracted tremendous attention toward settling issues of energy crisis. Copper iodide (CuI) and silver iodide (AgI) have been widely applied as hole transport layers (HTLs) , In addition, they both exhibit α, β, and γ crystalline phases, which transformed with different temperatures. − Moreover, γ-CuI and γ-AgI stable at room temperature can form a continuous solid solution copper silver iodide (Cu x Ag 1– x I) with varying components and a tunable band gap. , Investigations on the surface photovoltage (SPV) and transient SPV (TSPV) have been demonstrated to be critical for understanding carrier dynamics including carrier separation and carrier recombination behaviors for improving the efficiency of photovoltaic devices . Sankapal et al have studied crystal phases of AgI after the transition temperature by SPV spectroscopy.…”
