Self-healing polymers in rigid and flexible perovskite photovoltaics

Abstract

Over the past 10 years, perovskite solar cell (PSC) device technologies have advanced remarkably and exhibited a notable increase in efficiency. Additionally, significant innovation approaches have improved the stability related to heat, light, and moisture of PSC devices. Despite these developments in PSCs, the instability of PSCs is a pressing problem and an urgent matter to overcome for practical application. Recently, polymers have been suggested suggestion has been presented to solve the instability issues of PSCs and increase the photovoltaic parameters of devices. Here, first, the fundamental chemical bond types of self-healing polymers are presented. Then, a comprehensive presentation of the ability of self-healing polymers in rigid and flexible PSCs to enhance the various physical, mechanical, and optoelectronic properties is presented. Furthermore, valuable insights and innovative solutions for perovskite-based optoelectronics with self-healing polymers are provided, offering guidance for future optoelectronic applications.
