Electrical do** (that is, intentional engineering of carrier density) underlies most energy-
related and optoelectronic semiconductor technologies. However, for the intensely studied …

Halide perovskites (HPs) are potential game-changing materials for a broad spectrum of
optoelectronic applications ranging from photovoltaics, light-emitting devices, lasers to …

The emerging layered BiOX (X= Cl, Br, I) materials have been widely used for energy and
environmental applications. The BiOX crystal structure has been arranged by stacking of …

All highly-efficient organic–inorganic halide perovskite (OIHP) solar cells to date are made of
polycrystalline perovskite films which contain a high density of defects, including point and …

Perovskite solar cells (PSCs) have rapidly emerged as one of the hottest topics in the
photovoltaics community owing to their high power‐conversion efficiencies (PCE), and the …

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 …

Because interfacial nonradiative recombination (NRR) has a significant influence on device
performance, the minimization of interfacial NRR losses through interface engineering …

Defects play an important role in the degradation processes of hybrid halide perovskite
absorbers, impeding their application for solar cells. Among all defects, halide anion and …
