Prospect of double perovskite over conventional perovskite in photovoltaic applications

This article is an examination of the prospect of double perovskite material and its application in photovoltaic devices. Contemporary perovskite solar cells have some serious issues such as material toxicity, device hysteresis and material stability, despite their low-cost fabrication and high device efficiency. The topmost affecting factor is the use of toxic Lead which is also a natural hazard which leads to its restricted commercial usage. This review deals with the possibility of using Lead-free perovskite such as halides and oxides instead of Lead-based ones and merging simple perovskite materials to double perovskite to enhance their stability, optoelectronic property, and thermal conductivity. The research focuses on designing eco-friendly solar cells and the inclusion of double perovskite in optoelectronic devices. Scrutiny of current trends, experimental data, and related articles demonstrate that double perovskite has improved chemical compatibility and electrical conductivity by merging organic and inorganic compounds. Additionally, this article explores the prospect of double perovskite for alloying, doping, and cationic exchange in electronic structure. Further, the literature analysis shows that halogen-based double perovskite had excellent stability and optoelectronic characteristics. Also, the double perovskite-based assembled solar cell show enhanced power conservation and even more oxide-based blended in the mono clinic stage is found better for solar cell applications. The review concludes with challenges and recent developments in the photocatalytic application.
