Metal-oxide-based charge-transport layers have played a pivotal role in the progress of
perovskite solar cells. Yet metal-oxide/perovskite interfaces are often highly defective, owing …

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 …

In halide perovskite solar cells the formation of secondary-phase excess lead iodide (PbI2)
has some positive effects on power conversion efficiency (PCE) but can be detrimental to …

Perovskite solar cells (PSCs) with an inverted structure (often referred to as the p–i–n
architecture) are attractive for future commercialization owing to their easily scalable …

Controlling the perovskite morphology and defects at the buried perovskite-substrate
interface is challenging for inverted perovskite solar cells. In this work, we report an …

All-perovskite tandem solar cells hold the promise of surpassing the efficiency limits of single-
junction solar cells,–; however, until now, the best-performing all-perovskite tandem solar …

Inserting an ultrathin low-conductivity interlayer between the absorber and transport layer
has emerged as an important strategy for reducing surface recombination in the best …

Lewis base molecules that bind undercoordinated lead atoms at interfaces and grain
boundaries (GBs) are known to enhance the durability of metal halide perovskite solar cells …

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