“…The ratio of QE and wavelength represents the charge carriers produced by an SC in response to the photons that strike the cell . When the absorber thickness increases, a thick absorber layer can absorb more photons in the system and offers better QE characteristics. − Figure b shows that the ZnO, PCBM, and WS 2 as ETL demonstrate higher QE characteristics, whereas C 60 as ETL displayed poor and almost low QE characteristics.…”

Nontoxic and inorganic lead-free double perovskite La2NiMnO6 (LNMO) has achieved tremendous attention as an absorber layer of a solar cell (SC) structure due to its outstanding optoelectronic properties to support photovoltaic (PV) applications. In order to check the feasibility of LNMO as a potential SC absorber material, the structural, electronic, and optical properties of LNMO are computed within the realm of density functional theory (DFT). The computed energy band diagram confirms that LNMO is a degenerate semiconductor with an indirect band gap (E g) of ∼0.58 eV. In addition, the density of states (DOS) implies that the d-orbital electron of Mn and Ni elements and p-orbitals of O elements contributed significantly to the electronic conductivity of the material. The electronic charge density map and Mulliken population analyses manifest robust electronic charge accumulation around the O atom and the strong covalent bonding nature of Ni–O and Mn–O bonds, respectively. The strong absorption peaks in the infrared (20.0 eV), visible (2.6 eV), and near-ultra-violet (7 eV) regions reflect the true potential of LNMO as a PV material. Furthermore, the SCAPS-1D simulation tool is used to investigate the best-optimized electron transport layer (ETL)/LNMO/hole transport layer (HTL) SC configurations where PCBM, ZnO, C60, and WS2 are used as ETLs, while CuSCN, NiO, P3HT, PEDOT:PSS, ZnO, and CuSCN are used as HTLs. The WS2/LNMO/CFTS solar structure exhibited the best power conversion efficiency (PCE) of ∼20.18% among 24 different solar device combinations. The four best SC configurations are chosen for PV performance analysis through a variation in the ETL and absorber layer thicknesses. Furthermore, the impact of the variation of the series and shunt resistances of these SC structures are investigated. For deeper insights, the C–V plots, generation and recombination rates, J–V curves, and quantum efficiency plots are analyzed for the investigated configurations.

“…This increase suggests a reduction in the nonradiative recombination losses, and the inclusion of CHX can minimize the defect states in those perovskite films. 42,43 As shown in Figure 1d, XRD investigations are carried out to thoroughly evaluate the impact of CHX addition on the crystallinity of the FAPbI 3 layer. All of the films have characteristic diffraction peaks at 14.1°, 24.5°, and 28.3°w ithout a shift, which correspond to the (001), (111), and (002) planes of the FAPbI 3 perovskite phase, respectively.…”

It is essential and challenging to develop green and cost-effective solar cells to meet the energy demands. Solar cells with a perovskite light-harvesting layer are the most promising technology to propel the world toward next-generation solar energy. Formamidinium lead tri-iodide (FAPbI 3 )-based perovskite solar cells (F-PSCs), with their considerable performance, offer cost-effective solar cells. One of the major issues that the PSC community is now experiencing is the stability of α-FAPbI 3 at relatively low temperatures. In this study, we fabricated FAPbI 3 −PSCs using cyclohexane (CHX) material via a two-step deposition method. For this purpose, CHX is added to the formamidinium iodide:methylammonium chloride (FAI:MACl) solution as an additive and used to form a better FAPbI 3 layer by controlling the reaction between FAI and lead iodide (PbI 2 ). The CHX additive induces the reaction of undercoordinated Pb 2+ with FAI material and produces an α-FAPbI 3 layer with low charge traps and large domains. In addition, the CHX-containing FAPbI 3 layers show higher carrier lifetimes and facilitate carrier transfer in F-PSCs. The CHX-modified F-PSCs yield a high champion efficiency of 22.84% with improved ambient and thermal stability behavior. This breakthrough provides valuable findings regarding the formation of a desirable FAPbI 3 layer for photovoltaic applications and holds promise for the industrialization of F-PSCs.

“…Perovskite oxides have drawn a lot of attention due to their outstanding stability and mixed conductivity, as per the studies on dense diffusion barrier research. − By combining mixed conductor materials of La 0.8 Sr 0.2 CoO 3 and La 0.84 Sr 0.16 MnO 3 as YSZ or solid-state electrolyte as well as a layer of barrier to diffusion, respectively, F. Garzon et al developed sensors with the diffusion barrier layer of limited current density . The sensor’s performance under high oxygen content is adversely affected by the thin diffusion barriers produced by the magnetron sputtering process.…”

The oxygen sensors with limiting current derived from a dense diffusion barrier have an excellent advantage of detecting oxygen partial pressure by controlling the ratio of air and fuel in combustion environments. Therefore, AgNb 1−x Ti x O 3−δ (wherein x varies from 0.1 to 0.3) was prepared as such a dense diffusion barrier layer for sensor application. Among the investigated compositions as a new condensed barrier for the diffusion of sensors, AgNb 1−x Ti x O 3−δ (x = 0.1, 0.2, 0.3) exhibits oxygen ionic conductivities from 1.37 × 10 −4 to 5.78 × 10 −3 S•cm −1 in the temperature range of 600−900 °C and outstanding stable electrochemical properties. Herein, we employ these novel materials as dense diffusion barriers and 8 mol % zirconia stabilized by yttria (8YSZ) as a solid-state electrolyte for the fabrication of the oxygen sensors with limiting current. We observed a direct connection between the limiting current and oxygen content within the interval of 0.5−5.0 mol % at 800 °C and a low working voltage. The increase of Ti-doping amount in AgNbO 3 accelerates the sensing response to oxygen gas and promotes the service life of the sensor.
