Abstract

SrS/Zr films were grown using an electrochemical deposition technique. The spectrum is polycrystalline with a cubic structure and a noticeable (111) peak. The addition of 0.01 mol of zirconium dopant increases the peak intensity, confirming successful doping. Precursor temperature affects peak intensity, indicating film crystallinity. The spectrum is cubic with a distinct (111) peak and is polycrystalline. Peak intensity rises with the addition of 0.01 mol zirconium dopant, implying dopant acceptance. Peak intensity grows with higher precursor temperature, indicating film crystallite. Cloudlike precipitates appear on the film surface due to variations in precursor temperature. The cloudlike precipitate recircled and created a dense cloud on the film surface with increasing precursor temperature. The SrS material with doping demonstrated consistent deposition and complete substrate coverage by nanoparticles for photovoltaic applications. The synthesized films have an energy bandgap of 1.23 eV to 1.50 eV.
