The deposition of large ammonium cations onto perovskite surfaces to passivate defects and
reduce contact recombination has enabled exceptional efficiency and stability in perovskite …

Abstract 3D perovskite solar cells (PSCs) have shown great promise for use in next‐
generation photovoltaic devices. However, some challenges need to be addressed before …

Since the first introduction of the organic–inorganic hybrid perovskite in the field of
optoelectronics, extraordinary progress in both the photoelectric-conversion-efficiency and …

The disorderly distribution of defects in the perovskite or at the grain boundaries, surfaces,
and interfaces, which seriously affect carrier transport through the formation of nonradiative …

The surface of a semiconductor often has a key role in determining its properties. For metal
halide perovskites, understanding the surface features and their impact on the materials and …

Rapid progress in the efficiency of hybrid lead halide perovskite photovoltaics surpassed the
semiconductor thin-film solar cells such as CdTe (cadmium telluride), CZTS (copper zinc tin …

Introducing fluorine (F) groups into a passivator plays an important role in enhancing the
defect passivation effect for the perovskite film, which is usually attributed to the direct …

Almost ten years after their first use in the photovoltaic (PV) field, perovskite solar cells
(PSCs) are now hybrid devices that, in addition to having reached silicon performance, can …

Abstract Two‐step‐fabricated FAPbI3‐based perovskites have attracted increasing attention
because of their excellent film quality and reproducibility. However, the underlying film …

Abstract Low‐dimensional Ruddlesden–Popper perovskites (RPPs) exhibit excellent
stability in comparison with 3D perovskites; however, the relatively low power conversion …
