Development of perovskite films with photoluminescent properties for building applications

Energy-efficient materials such as perovskites have attracted attention due to their characteristics, low manufacturingcosts and variety of production methods. These materials can be used in different applications to promote the development of smart cities. Previous work reports instability of perovskites exposed to air, humidity and temperature, so currently continues to study structures with sustainable materials that provide greater durability. Based on this, the present research explores the synthesis of a perovskite coating in biopolymer matrix to promote the use of environmentally friendly materials in construction. The proposed films were synthesized from polysaccharides, lead acetate and cesium bromide dissolved in a dimethyl sulfoxide and dimethylformamide system under ambient conditions. Finally, different techniques were used to study the optical, morphological and structural properties of the material confirming its application as homogeneous and photoluminescent films with a content of organic ligands for the formation of perovskite.
