Abstract
Perovskite solar cells (PSCs) offer unique advantage of enabling lightweight and flexible power sources compared to the commercially available rigid wafer-based silicon solar cells, while their power conversion efficiencies are now nearly comparable. To ensure high performance, flexibility and lightweight characteristics in flexible perovskite solar cells and modules, it is essential to develop electrodes that are highly conductive, highly transparent, flexible and thin. In this review, we first highlight important technical metric, figure of merits (FoM), that reflects not only the optical and electrical properties of the transparent electrodes but also their mechanical flexibility. Then, we review recent advancements in transparent conductive electrodes for flexible perovskite solar cells, focusing on various materials and designs including conducting polymers, metal nanowires and meshes, carbon-based nanomaterials, transparent conducting oxides and other novel materials. Lastly, we discuss the challenges and future prospects toward commercialization of flexible perovskite solar modules.
期刊介绍:
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
