Perovskite has the basic formula ABX3 where A and B have cations and X has an anion group. This material belongs to a significant class with numerous remarkable properties, including high-transition-temperature superconductivity, ferromagnetic, piezoelectric, ferroelectricity, and photoelectrochemical sensitivity. Perovskite substances have drawn much attention in the photovoltaic process, because of their energy conversion phenomena, high electron mobility, and ionic conductivity properties. Perovskite structured stannates, namely those with the formula (MSnO3) where M is alkali, alkaline earth metals, and lanthanides have been the subject of extensive research because of their intriguing structural and physical attributes, including optical and magnetic features. Perovskite heterojunctions based on stannates are essential for energy-related applications, especially solar cells. Their capacity to improve charge separation and light absorption boosts both the reliability and effectiveness of photovoltaic systems, offering bright futures for the development of renewable energy technology. Because of the special qualities of stannate-based perovskite heterojunctions that result from the integration of stannate and perovskite features, bandgaps, charge carrier mobility, and catalytic activities can all be customized. This review gives an overview of the stannate-based perovskite heterojunction, with their synthesis techniques and uses, providing insight into their possible roles in developing sustainable technologies and materials.
