This review provides succinct yet comprehensive insights into the development of f-PSCs, paving the way for their integration into various applications and highlighting their potential in the renewable energy landscape.

Recent cutting-edge strategies for flexible perovskite solar cells toward commercialization

Flexible perovskite solar cells (f-PSCs) have attracted tremendous attention as a self-power supply for various electronic devices that require high power, various form-factors, and a light-weight power supply. In addition, many studies have investigated scalable and continuous roll-to-roll (R2R) processes, with the aim of mass production and commercialization of f-PSCs. In this review, we focus on the strategies developed in the last three years toward commercialization of high-efficiency, lightweight and ultra-flexible, and reliable perovskite solar modules (f-PSMs). Furthermore, the research perspectives of f-PSCs regarding their future development are addressed.
