Abstract

Research of lead-free perovskite solar cells has gained speedy and growing attention with urgent intent to eliminate toxic lead in perovskite materials. The environmental friendliness and excellent thermal stability proves of stable perovskite Cesium Tin Iodide (CsSnI₃) as one of the promising materials for their potential application in solar field. In this paper, fabrication and characterization of CsSnI₃ perovskite layer has been reported. Fabrication of CsSnI₃ perovskite layer was made by spin coating method. One step coating processed CsSnI₃ layer have characterized by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FESEM). Optical properties of layer have investigated by Vis-NIR spectrophotometer. It reveals that CsSnI3 perovskite layer possess good absorption in the visible spectrum. XRD result confirms the crystal structure of orthorhombic phase with dominating peak at 27.5⁰ (2*Θ) corresponding (202) planes. Dense distributions of polycrystalline CsSnI₃ perovskite layer were recorded by FESEM images.
