Applications of emerging metal and covalent organic frameworks in perovskite photovoltaics : materials and devices

Abstract

Perovskite solar cells (PSCs) have emerged as the next generation photovoltaic technology due to their high power conversion efficiency and solution-based fabrication process. The performance of PSCs relies on the composition of each layer and the interface properties between layers. Hence, the integration of novel materials into PSCs presents a viable strategy for enhancing device performance. Metal–organic frameworks (MOFs) and covalent organic frameworks (COFs) have recently emerged as promising materials for improving the efficiency and stability of PSCs. These materials offer a diverse range of tunable physicochemical properties and functionalities. This comprehensive review aims to provide an in-depth summary of the progress in utilizing MOFs/COFs in PSCs. The review covers key aspects such as their electronic properties, synthesis methods, and various applications within PSCs, including their role as different components and their potential as lead absorbents. Finally, the review outlines important challenges and highlights future prospects for advancing this technology.
