Abstract Lead halide perovskite solar cells have been emerging as very promising candidates for applications in indoor photovoltaics. To maximize their performance, it is of critical importance to suppress intrinsic defects the active layer. Herein, a facile solvent‐engineering strategy developed effective suppression both surface and bulk lead cells, leading high efficiency 35.99% under illumination 1000 lux Cool‐white light‐emitting diodes. Replacing dimethylformamide (DMF) with N...
This study investigates the structural, electronic, optical and mechanical properties of K 2 YCuX 6 ([Formula: see text]) using advanced density functional theory (DFT) within full potential linearized augmented plane wave (FP-LAPW) framework. Structural stability was validated through tolerance factor calculations, yielding values 0.96 0.97 for YCuCl YCuBr , respectively, while formation energy analysis confirmed thermodynamic with [Formula: text]1.71 text]1.73[Formula: text]eV/atom....
Present work reports a simple, cost-effective and facile approach for electrochemical sensing of 2-nitrophenol (2-NP) as the model analyte using silver thin film electrodes. Thickness controlled films are grown on ITO glass substrates at 400°C varying deposition times 10–45 minutes methanol solution triflouroacetate (Ag(CF3COO)), via aerosol assisted chemical vapor (AACVD). XRD, XPS, SEM EDX analysis verified presence crystalline phase pure elemental with micro/nanometer dimensions whereas...
Modification of conventional photoanode with oxide nanoparticles is a practical tactic to improve the performance electrochemical devices. In this study, erbium (Er 2 O 3 ) were mixed TiO paste and photovoltaic dye-sensitized solar cell (DSSC) was investigated. The highest power conversion efficiency 6.39% reached 1 wt.% Er in photoanode, while similar condition device pure achieved 3.54%. This improvement attributed declining charge recombination, improved open-circuit voltage short-circuit...
Abstract 1D hematite ( α ‐Fe 2 O 3 ) nanorods were synthesized in the presence of rice starch solution. The size was about 250 nm and 50 length diameter, respectively. possessed a single phase without any impurities crystal defects. obtained employed as an adsorbent for lead (II) removal. isotherms kinetic studies indicated that our material would be potential candidate heavy metal adsorption
Cerium oxide (CeO2) nanoparticles (NPs) were mixed with titanium dioxide (TiO2) in different wt.% to obtain an improved composite photoanode better electron-injection property. Using these materials, dye-sensitized solar cells fabricated, and photovoltaic performances evaluated. For performance comparison, a cell pure TiO2 as was also prepared. Devices fabricated using photoanodes 1%, 3%, 5%, 7% of CeO2 showed power conversion efficiency (PCE) 7.0%, 5.68%, 5.64%, 3.97%, respectively....
A new chemical method is developed for the preparation of a unique one-dimensional (1D) Sn(<sc>iv</sc>) hydroxide nanofluid.
Abstract Large‐scale, uniform, monodisperse La CO 3 OH cherry‐blossom‐like nanogears and/or nanocubes have been synthesized under hydrothermal reaction conditions. Upon the addition of only 5 mol% Ca 2+ ions into a nitrate salts solution with pH 8.5, crystals novel cubic or nanogear structures are formed in hexagonal phase. The reactions were carried out without template catalysts. Both 24 hour and 48 yield 100% pure no irregular particles. We examined photoluminescence properties...
