Abstract
The present disclosure is related to a perovskite films manufacturing process (CH3NH3Pbl3-xClx) which are used to manufacture of solar cells, such as the chemical bath deposition or the chemical evaporation al low temperatures. This manufacturing method allows the production of homogeneous large-scale perovskite films and also a control over the thickness of the films, on any substrate not soluble in water. Temperatures greater than 100°C, are not used in this process and does not require special conditions; in addition, allows the deposit without area limitation. With this process it is possible to deposit lead sulphide as a precursor for perovskite. Subsequently, there comes a treatment with iodine vapor, process in which only 80°C is necessary to generate them and to react with lead sulfide to transform the same into lead iodide. Finally, these films are exposed to methylammonium chloride vapors at 145°C to obtain perovskite.
