Abstract

The power conversion efficiency achieved in three-dimensional (3D) perovskite solar cells (PSCs) is already competitive with that of commercial silicon solar cells. Achieving long-term stability under operation conditions is critical for reaching market success for PSC applications. Despite impressive progress over the past few years on fundamental understandings and technical innovations for improving PSC stability, the stability of PSCs against moisture/heat/light is still a key focus of research efforts for PSC development. Recent studies suggest that the long hydrophobic organic spacer in two-dimensional (2D) perovskites is helpful to improve perovskite stability, but 2D perovskites seem limited on obtaining high-performance solar cells due to its wide optical bandgaps and limited charge transport. To overcome this challenge, 3D/2D multidimensional perovskites—with an intermediate dimensionality between 3D and 2D—has recently emerged as a potential candidate to simultaneously maintain long-term stability and high performance. In this review, we first present a detailed discussion of the structure of 3D/2D multidimensional perovskites and their unique properties. Second, we discuss the stability of 3D/2D multidimensional perovskite and 2D perovskite as interface engineering layer-based solar cells. Finally, we summarize and outline the perspectives toward high-performance 3D/2D multidimensional perovskite-based solar cells.
