Antimony selenide (Sb2Se3) has recently been intensively investigated and achieved significant advancement in photoelectrochemical (PEC) water splitting. In this work, a facile one-step hydrothermal method for the preparation of Sn-doped Sb2Se3 photocathodes with improved PEC performance was investigated. We present an in-depth study enhancement using capacitance–voltage (CV), drive-level capacitance profiling (DLCP), electrochemical impedance spectroscopy (EIS) techniques. The incorporation Sn2+ into results increased carrier density, reduced surface defects, charge separation, thereby leading to performance. With thin absorber layer (270 nm thickness), photocathode exhibits photocurrent density 17.1 mA cm–2 at 0 V versus RHE (VRHE) compared that undoped (14.4 cm–2). This work not only highlights positive influence Sn doping on but also showcases synthesize doped optoelectronic properties.

ABSTRACT Cadmium telluride exhibits unique photoelectric properties, making it suitable for use in thin‐film solar cell modules. This study subjected thermally evaporated cadmium thin films to post‐deposition irradiation with argon plasma at various powers (20–40 W). The influence of on the structure, bulk chemical composition, surface chemistry, and optical properties was investigated. Additionally, impact treatment photocurrent photoresponse evaluated. Optimal performance achieved a 30 W treatment, resulting larger crystallite sizes reduced roughness, wider band gap, increased absorption due creation plasma‐induced defects. These exhibited relatively high electrical conductivity, lower photoresponse.

Abstract This work reports a new thermal treatment approach to obtain [001]‐oriented Sb 2 Se 3 film, which consists of preliminary annealing the layer before its selenization. Among different temperatures assessed, one at 200 °C followed by selenization (Sb (Sb‐A200)) results in considerably high texture coefficient [001] direction, whereas film obtained only non‐annealed (Sb‐NA)) features preferential orientation [ hk 0] direction. In terms photoelectrochemical (PEC) performance for H generation, (Sb‐A200)/CdS/TiO /Pt delivers substantial photocurrent density −5.65 mA cm −2 0 V RHE , is 10 times higher compared (Sb‐NA)/CdS/TiO film. Additionally, employment step stable PEC over 7000 s, meaning that photocorrosion minimized. The improved attributed better crystallinity and composition closer stoichiometric condition, as well direction favors charger carriers' transportation. At last, findings this feature an innovative further improve generation from water splitting.

This study investigates the low-temperature hydrogen plasma treatment approach for improvement of generation through waste aluminum (Al) reactions with water and electricity via proton-exchange membrane fuel cell (PEM FC). Waste Al scraps were subjected to ball milling treated using two different regimes: Diode magnetron-initiated treatment. Hydrolysis experiments conducted powders treatments, varying molarities, reaction temperatures assess generation, kinetics, activation energy. The results indicate that significantly enhances hydrolysis kinetics compared untreated or those diode-generated plasma. Analysis chemical bonds revealed takes advantage by promoting a dual procedure: Surface cleaning nanocluster deposition on top powders. Moreover, it was modeled such H2 could penetrate up 150 Å depth. Meanwhile, tests demonstrate only 0.2 g powder can generate approximately 1 V over 300 s under constant 2.5 Ω load 1.5 2700 spinning fan.
