Synthesis and characterization of a hybrid perovskite to be applied as an absorbent layer in solar cell

Abstract

Abstract This study is based on the synthesis and characterization of a hybrid perovskite based on tin chloride and methylammonium (CH3NH3SnCl3) as an absorbent layer in solar cells. Preparation of the hybrid material was carried out using the wet method from a precursor of methylammonium chloride CH3NH3Cl and tin chloride (II) (SnCl2). The solid obtained was heated to a temperature of 60°C in order to obtain the final product. The hybrid material was then characterized by X-ray diffraction, Raman spectroscopy and scanning electron microscopy. The structural and morphological results showed the characteristic traits corresponding to the material. The formation of conglomerates with irregular spherical geometry and cubic forms associated with the precursor of tin chloride were also present. The application of this type of perovskite in solar cells is preferable due to its environmentally friendly impact, making it a promising material for photovoltaic technology.
