锑基钙钛矿材料体系在太阳能光伏中的演化与前沿发展：一项全面综述

Abstract It is now an established fact that Lead (Pb) based perovskites are the front-runners as a photovoltaic material in terms of low production cost and high device efficiency . However, due to the inherent toxicity of Lead, efforts are being made to replace Lead with more stable and less toxic alternatives. Antimony-based perovskites have lately grabbed the attention of PV research communities. However, developing a stable and reliable Sb-based perovskite for enhanced PV performance necessitates optimizing methods such as doping, material engineering, stoichiometry, and adjustments to lattice dimensions. Uncovering valuable insights within each of these domains is often a challenging endeavour. The scope of the study can also be broadened to encompass deposition and preparation techniques alongside the exploration of material properties. The field of perovskite materials for PV is expanding so fast that keeping track of the updates in all these domains and the state-of-the-art in the field is quite cumbersome. Hence, this review is an effort to comprehensively cover the state-of-the-art developmental stages in the Sb-based perovskite material system and the challenges from the perspectives of science and technology in the context of above domains. In particular, the recent surge of perovskites with 2D structures has led to significant innovations in the Sb-based perovskite materials systems, and the relevant challenges in perspective of 2D structures vis-à-vis the bulk materials are unparalleled. The compilation of such developments and subsequent challenges are scarce so far. The review also provides a brief account of such developments and their future prospectus.
