用于光伏应用的热蒸发SnSe纳米结构层的研究

Solar modules with nanostructures photovoltaic technology generate power at an economical cost per watt. They are ideal options for both building-integrated photovoltaic applications and large-scale solar farms. In this work, thermal vapour deposition has been employed to create orthorhombic tin selenide nanostructures on glass and alumina substrates to analyze its characteristics for photovoltaic applications. The morphological, structural characterization for the deposited nanostructures were methodically analyzed and examined using XRD, SEM, and AFM, respectively. Further the influence of the substrate temperature and substrate material type on diverse nanostructure characteristics onto alumina and glass substrates were also examined. A mixed phase appears as a function of temperature, according to XRD analysis. Electron dispersive spectroscopy (EDS) reveals the presence of oxygen at high temperatures and confirm that all the required elements are present. Atomic force microscopy (AFM) images were utilized for analyzing the surface topography of the generated nanostructures. The acquired phase and the selenium temperature had a notable impact on optical studies. The photovoltaic characteristics of the nanostructures over alumina substrates were also investigated.
