Electrochemically Synthesize SrSe/ZrSe Heterostructure Material for Photovoltaic Application

In this research, SrSe/ZrSe super-lattice was synthesized using an electrochemical deposition technique. The XRD pattern reveals a polycrystalline cubic structure with a diffraction angle at ۲ thetas ۱۱.۹۳o, ۱۳.۹۷o, ۲۰.۸۷o, and ۲۷.۷۱o. Introducing ZrSe increased the peak intensity, signifying improved film crystallinity. Time had a significant effect on the electrical parameters and thickness of SrSe/ZrSe super-lattice. The film's absorbance decreases as its wavelength increases. The film's transmittance increases with wavelength. The SrSe/ZrSe synthesized at normal time had a bandgap energy of ۲.۵۰ eV. As the time of deposition increased, the bandgap energy decreased to ۲.۳۹ - ۲.۲۲ eV.
