Cu2MgSnS4 (CMTS) films are successfully deposited on glass substrates by spray pyrolysis technique. The influence of sprayed volume (Vs), Vs = 80, 100, 150 and 200 ml, on CMTS physical properties was investigated using X-ray diffraction, Raman spectroscopy, scanning electron microscopy (SEM), UV–vis and Impedance analysis spectroscopies. Structural properties analysis confirms the stabilization of the kesterite structure with (112) preferential orientation where the best crystalline quality is obtained for Vs = 100 ml. The morphological study shows smooth surface for Vs = 100 ml. Optical measurements exhibit a high absorbance in both visible and IR regions with a band gap energy in the range [1.55–1.79] eV. All Nyquist plots reveal a single electrical relaxation phenomenon. CMTS thin films grown with Vs = 100 ml proven it high performance toward moisture. Moreover, the photocatalytic activity test toward the degradation of methylene blue under sunlight irradiation demonstrates an efficiency of 94% for the sample grown with Vs = 100 ml.
