Role of Perovskite-Type Oxides in Energy Harvesting Applications

Perovskite type oxide (PTO) is an extensively studied material over the past decade. Deformations occur as a consequence of variances in their ionic radii and electronegativity, which come from the production of oxygen or cation deficiencies, or alterations in their respective bonding angles. The perovskites' defects and order–disorder crystal structures result in a wide range of functional characteristics. This paper reviews the contribution of perovskite-based oxides in these applications. In this context, the future scope of these materials has been investigated to enhance the performance parameters like specific capacity, power conversion efficiency, energy density, and cycle life. This research will aid in the selection of suitable perovskite materials.
