In-depth characterization of physical proprieties of SnS:Mg thin films fabricated by ultrasonic spray for solar cell applications
Ultrasonic spray pyrolysis (USP) technique has been used to deposit pure and magnesium (Mg) incorporation Tin Sulphide (SnS:Mg) thin films at 350 °C by varying the Mg impurities concentration (2%, 4%, 6% and 8%). X -ray diffraction patterns confirms the orthorhombic crystal structure of SnS:Mg thin...

Summary: | Ultrasonic spray pyrolysis (USP) technique has been used to deposit pure and magnesium (Mg) incorporation Tin Sulphide (SnS:Mg) thin films at 350 °C by varying the Mg impurities concentration (2%, 4%, 6% and 8%). X -ray diffraction patterns confirms the orthorhombic crystal structure of SnS:Mg thin films. Structural parameters such as crystallite size, microstrain and dislocation density were determinated. SEM images displayed the influence affected of SnS films surface morphology by the change of Mg incorporation concentration. The optical band gap energy were determinated by measuring the transmission which showed a low value of 1.59 eV with a strong emission peak of photoluminescence spectra observed at 421 nm for 6% of Mg incorporation concentration. Hall Effect measurement confirm the p-type conductivity of the SnS:Mg film and presented a very low resistivity of 1.58 × 10
