Introduction to Perovskite

Halide perovskite semiconductors have emerged as exceptionally promising materials for a plethora of optoelectronic device applications ranging from energy harvesting/generation to lighting and sensing due to their inherent chemical and photophysical properties. It took only just over a decade to reach the door of commercialization. The range of structural and compositional tunability has made its application more diverse and specific simultaneously. This chapter focuses on the evolution of perovskite material from its inception to its current applications, as well as discusses the exploration of its fundamental properties. The chapter also gives insights into understanding the material’s physical and chemical properties and thus investigates avenues for implementation in different optoelectronic device applications. The chapter concludes with a discussion of the technological barriers towards commercialization, such as toxicity and stability.
