The optical performance of the perovskite materials is enhanced through material optimization. This work seeks to establish the role of antisolvent and additive with new material composition on light absorption property. Due to this composition we extended the wavelengths to near Infrared range which is a suitable property for photovoltaic device. From the features of the film, optical parameters, together with anti-stoke shift and dielectric constant were calculated using Cauchy dispersion formalism. Based on our results, dielectric constant which is considered as a design parameter for photovoltaic cell and an unusual anti-stoke shift were observed. In sum, the optical properties are tied to material composition, morphology and technique used.
Key words: Perovskite / photovoltaic / antisolvent / optical properties
