Interest in photovoltaics (PVs) based on Earth-abundant halide perovskites has increased
markedly in recent years owing to the remarkable properties of these materials and their …

The A cation in ABX3 organic-inorganic lead halide perovskites (OLHPs) was conventionally
believed to hardly affect their optoelectronic properties. However, more recent developments …

Controlling the crystallinity and surface morphology of perovskite layers by methods such as
solvent engineering, and methylammonium chloride addition,,,–is an effective strategy for …

Achieving both high efficiency and long-term stability is the key to the commercialization of
perovskite solar cells (PSCs),. However, the diversity of perovskite (ABX3) compositions and …

A myriad of studies and strategies have already been devoted to improving the stability of
perovskite films; however, the role of the different perovskite crystal facets in stability is still …

Incorporating mixed ion is a frequently used strategy to stabilize black-phase formamidinum
lead iodide perovskite for high-efficiency solar cells. However, these devices commonly …

The stabilization of grain boundaries and surfaces of the perovskite layer is critical to extend
the durability of perovskite solar cells. Here we introduced a sulfonium-based molecule …

Perovskite light-emitting diodes are an emerging light source technology. However, similar
to perovskite solar cells, poor operational stability remains an obstacle for commercial …

Abstract Two-dimensional (2D) and quasi-2D modifications of three-dimensional (3D)
perovskite active layers have contributed to advances in the performance of perovskite solar …

The energy landscape of reduced-dimensional perovskites (RDPs) can be tailored by
adjusting their layer width (n). Recently, two/three-dimensional (2D/3D) heterostructures …
