Abstract This research explores the capabilities of SnO 2 thin films in renewable energy, with a focus on hydrogen generation through photoelectrochemical (PEC) water splitting. X‐ray diffraction (XRD) analysis identifies tetragonal rutile crystal structure, indicating highly crystalline phase free from secondary phases. A crystallite size about 40 nm, determined via Debye–Scherrer formula, suggests enhanced catalytic suitability for PEC applications. Scanning electron microscopy (SEM) reveals web‐like, rough surface, beneficial splitting by providing high surface area that improves light absorption and charge transfer. The interconnected nanoparticles, averaging 28.63 nm size, create active sites further boost photocatalytic performance. UV‐Vis spectroscopy shows strong UV range (300–330 nm) limited visible absorption, consistent wide bandgap approximately 3.63 eV. With 72.5% transparency spectrum, proves effective as transparent conducting oxide (TCO), advantageous optoelectronic devices. Electrochemical impedance (EIS) highlights low transfer resistance, linear sweep voltammetry (LSV) significant photocurrent density, supporting 's effectiveness solar‐to‐hydrogen (STH) efficiency is 3.526% at 0.8 V, demonstrating proficiency production. Additionally, chronoamperometry confirms film's stability responsiveness. production rate 3256.93 mol/g over 6 h attributed to porous structure film, which enhances harvesting evolution reaction. These findings establish promising material energy
