Flexible perovskite solar cells (F-PSCs) are revolutionizing renewable energy technologies through their unique combination of flexibility, lightweight properties, and exceptional low-light performance, effectively transcending the limitations of conventional photovoltaics. These innovative F-PSCs enable seamless integration with distributed energy systems and end-user applications, offering customized solutions across diverse sectors. Their remarkable adaptability facilitates transformative applications in building-integrated photovoltaics (BIPV), where they harmonize high-efficiency power generation with architectural aesthetics; vehicle-integrated PV systems that provide lightweight energy solutions for electric vehicles; agrivoltaic implementations supporting sustainable agriculture; and portable power systems for consumer electronics. The widespread application of F-PSCs not only facilitates the penetration of renewable energy technologies into consumer-grade and mobile scenarios, but also plays a pivotal role in developing advanced “Photovoltaic-Energy Storage-Direct Current-Flexibility” building systems and accelerating the realization of “Dual Carbon” target.
