“…In addition, the intensity of the diffraction peaks decreases with increasing Al concentration, the augmentation of which reduces the film thickness. These results indicate to uniform distribution of Al ions across the SnO 2 lattice [42] and agree with some reports [41,43] .…”

Transparent conducting aluminum doped tin oxide thin films were prepared by sol-gel dip coating method with different Al concentrations and characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), UV–Vis spectrophotometry and photoconductivity study. The variation observed in the properties of the measured films agrees with a difference in the film's thickness, which decreases when Al concentration augments. X-ray diffraction analysis reveals that all films are polycrystalline with tetragonal structure, (110) plane being the strongest diffraction peak. The crystallite size calculated by the Debye Scherrer’s formula decreases from 11.92 to 8.54 nm when Al concentration increases from 0 to 5 wt.%. AFM images showed grains uniformly distributed in the deposited films. An average transmittance greater than 80% was measured for the films and an energy gap value of about 3.9 eV was deduced from the optical analysis. Finally, the photosensitivity properties like current–voltage characteristics, I ON/I OFF ratio, growth and decay time are studied and reported. Also, we have calculated the trap depth energy using the decay portion of the rise and decay curve photocurrent.

Sn metal is a preferable choice as anode material for aqueous acidic batteries due to its acid‐tolerance, non‐toxicity, and ease of recycling. However, the large size and irregular deposition morphology of polyhedral Sn particles are bad for constructing stable and high‐capacity Sn metal anode because of severe hydrogen evolution and metal shedding. To tackle this critical issue, 4‐tert‐octylphenol pentaethoxylate (POPE) is used as an electrolyte additive to generate a thin‐film Sn anode with reversible stripping/plating behavior. POPE can not only induce homogeneous surface chemistry by adsorbing on the Sn surface via coordination bonds but also inhibit hydrogen evolution by modulating the solvation shell of Sn2+. The Sn film anode delivers improved electrochemical stability over 480 h with satisfactory rate performance and low polarization. Moreover, the as‐assembled PbO2//Sn battery can also provide outstanding durability at 10 mAh cm−2. This work offers new inspiration for developing a reversible Sn metal film anode.
