The Aluminium content was varied from Pure to 5 Wt.% to study its effect on structural, surface, optical, and electrical properties. X-ray diffraction results confirm the formation of polycrystalline PbS with a cubic crystal structure. The films show a strong preferential orientation along the (200) plane. The crystallite size ranges between 18 and 20 nm and changes slightly with doping level. Optical studies show a clear increase in direct band gap from 1.54 eV for the Pure PbS film to 1.66 eV for the 5 Wt.% Al-doped PbS film. This shift indicates a modification in electronic structure and defect states resulting from Aluminium incorporation. Electrical analysis shows lower resistivity and higher carrier concentration at 2.5 Wt.% Al doping. The results indicate that controlled Al doping improves the optoelectronic behaviour of PbS thin films and makes them suitable for low-cost solar cell applications.</p>2026-04-10T00:00:00+00:00Copyright (c) 2026 Rigana Begam M, Elavarasan S, Arulanantham A.M.S
