Can two-dimensional graphdiyne-based materials be novel materials for perovskite solar cell applications?

Abstract

Abstract Two-dimensional (2D) graphdiyne (GDY)-based materials have attracted attention in the solar cell research community owing to their unique physicochemical properties and hydrophobic nature which can serve as moisture resistance from the surrounding medium. Benefiting from these, the performance and stability ofperovskite solar cells (PSCs) can be greatly improved via the addition of 2D GDY-based materials. This mini-review summarizes the recent development of 2D GDY-based materials for PSC application. The roles of 2D GDY-based materials, such as hole transporting material, electron transporting material, dopant material in perovskite film and interfacial layer, are discussed in detail. Moreover, we provide future perspectives in this field, aiming to help further progress efficient and stable 2D GDY-based materials in PSCs.
