“…Nevertheless, oxide perovskites and their derivatives have been extensively used in many technologies, reflecting their versatile properties. , Due to their compositional and structural flexibility, oxide perovskites show several other attractive properties including superconductivity, ferroelectricity, magnetoresistance, and ionic conductivity. Although halide perovskites have shown considerable promise in photovoltaic (PV) applications due to their superior photovoltaic properties such as extremely high optical absorption coefficient, super long carrier diffusion length, and low-temperature solution processability, the practical use of it and its commercialization is still not always possible because of the instabilities associated with moisture, temperature, and other environmental factors. On the other hand, double perovskite oxides and their derivatives have shown greater applications in electrocatalysis, photocatalysis, and photovoltaics attributed to their superior stability.…”

The quest for clean energy conversion has become one of the most important efforts for tackling the greenhouse effect for a sustainable environment. This involves energy-scavenging processes like photovoltaics and catalysis, which have been manifested using the solar spectrum. For high-efficiency and durable conversion processes, the search for the low-cost, stable, and environment-friendly functional materials is elusive. In the field of solar cells and catalysis, double perovskite oxides (DPOs) have emerged as potential candidates in recent years. Through compositional tuning and band gap engineering, a plethora of materials are being developed for pertinent applications in this field of energy. Oxide perovskites possess the advantage of a high carrier lifetime compared to that with halide perovskites, which can be beneficial for energy applications. In this perspective, we have presented theoretical investigations focusing on the different types of double perovskite oxides based on the composition space in a systematic manner. Corresponding electronic and optical properties are discussed along with a future outlook on the novel routes to find efficient members in this family.
