Flexible perovskite solar modules: Fabrication strategies and future prospects

Abstract

Flexible perovskite solar cells have attracted considerable attention owing to their light weight, mechanical flexibility, and broad potential for applications. With their rapid development, research emphasis has progressively moved from small-area devices toward flexible perovskite solar modules (F-PSMs). However, compared with rigid modules, studies on F-PSMs remain relatively limited, and the fabrication of flexible modules that are simultaneously efficient, stable, and compatible with industrial-scale production still represents a major challenge. In this review, we systematically summarize the fabrication techniques developed for F-PSMs and analyze and compare their effects on large-area film formation, device integration, module efficiency, mechanical durability, and operational stability. Finally, we discuss the commercialization prospects of F-PSMs and propose feasible strategies to promote their industrialization, aiming to provide useful guidance for their future development and practical applications.
