Abstract
Perovskite solar cells are an emerging technology that exploits the self-assembly and highly tunable bandgap properties of perovskite materials. Because of their low manufacturing cost, thin films of perovskites have attracted enormous interest and witnessed great progress. The power conversion efficiency of these devices has improved from 3.8% to 25.8%, which is a significant step forward. The formulation of innovative materials with the proper replacement of lead in perovskites is essential to reduce lead toxicity. Here, we examine the difficulties encountered in the commercialization of perovskite devices, such as material and structural stability, device stability under high temperature and humidity conditions, lifetime, and manufacturing cost. This review addresses issues such as device engineering, performance stability against the harsh environment, cost-effectiveness, recombination, optical, and resistance losses, large-area solar cell module issues, material cost analysis, module cost reduction strategy, and environmental concerns, which are important for the widespread acceptance of perovskite-based solar devices. The applications and market growth prospects of perovskite cells are also studied. In summary, we believe there is a great opportunity to research high-performance, long-lived perovskites and cells for energy applications.
