In recent years, 2D Ruddlesden–Popper (2DRP) perovskite materials have been explored
as emerging semiconductor materials in solar cells owing to their excellent stability and …

Perovskites with low ionic radii metal centres (for example, Ge perovskites) experience both
geometrical constraints and a gain in electronic energy through distortion; for these reasons …

Carbon‐based inorganic perovskite solar cells (C‐PSCs) have attracted intensive attention
owing to their low cost and superior thermal stability. However, the bulk defects in …

Summary Dion-Jacobson (DJ) phase 2D perovskites have received wide attention due to
their higher stability compared with 3D ones. However, some of the reported DJ 2D …

Metal halide perovskites have drawn significant attention for their promising physical
properties and their possible application in solar cells and light‐emitting diodes. Research …

Hybrid organic–inorganic perovskites (HOIPs) have garnered widespread interest, yet
stability remains a critical issue that limits their further application. Compared to their three …

Hybrid lead halide perovskites have been intensively investigated due to their structural
diversity and outstanding optoelectronic properties. As emerging semiconducting materials …

Metal-halide perovskitoids with corner-, edge-, and face-sharing octahedra provide a fertile
“playground” for structure modulation. With low defect density, low ion migration, and high …

The elucidation of the structure–property correlation in 2D metal halide perovskite is a key
issue to understand the dependence of optical properties on structural distortions and to …

Abstract Two‐dimensional (2D) lead halide perovskites (LHPs) have shown great promises
for light‐emitting applications and excitonic devices. Fulfilling these promises demands an in …
