Hybrid perovskite thin film offers diverse advantages like low cost deposition techniques, less material consumption and superior optoelectronic properties. These merits including high voltage and high efficiency performance in a wide range of high light intensity are sufficient to distinguish perovskite thin films/devices from their contenders as a thin film technology with greater potential for industrial applications. Perovskite thin film technology demonstrates potency in a variety of applications in optoelectronic devices especially photovoltaic applications. The National Renewable Energy Laboratory (NREL) of the USA categorizes a number of thin films technologies including perovskite thin film, as emerging photovoltaics with the bulk of them yet to be commercially applied but are still in the research or developmental stage. In this chapter, various processing methods and material combinations as well as current trends in this technology are subjects of discussion.

Several data on the preparation of perovskite crystals have been obtained because samples/devices were prepared using films of different qualities. Identifying optimal conditions for perovskite material synthesis and thin film preparation as well as optimizing the properties will go a long way in reducing the disparities in the data obtained. The optimal composition management of various elements of perovskite remains an outstanding research. The chapter will pave the way for the optimum design of the synthesis process of perovskite-based devices for better performance. Further still, the study provides basis for explaining the effective optimizations of synthesis conditions and material properties.
