High‐Performance Self‐Powered Perovskite Photodiodes for Blue‐Light Detection Using Anisole‐Assisted Precursor Engineering

open access: yesSmall, EarlyView.
Anisole‐assisted precursor engineering provides a simple route to high‐quality perovskite films for self‐powered blue‐light photodetection. Anisole promotes grain growth and suppresses pinholes, reducing dark current while improving external quantum efficiency and detectivity.

Molecularly Regulated Dynamic Interfaces in 3D/2D Perovskites Enabled by Functional Pyridinium Ionic Liquids

open access: yesSmall, EarlyView.
1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Unraveling the Proton‐Induced Degradation Mechanism in Quantum‐Dots Light‐Emitting Diode for Space Applications

open access: yesSmall, EarlyView.
Low‐energy proton irradiation induces ligand detachment at the QD/ZnO interface in quantum‐dot light‐emitting diodes (QLEDs). The exposed ZnS surface interacts with ZnO defects, generating a high density of interfacial trap states that promote electron trapping, suppress charge injection, and accelerate non‐radiative recombination, ultimately leading ...

Direct Synthesis of Short‐Chain Alkylammonium Capped FAPbI3 Perovskite Nanocubes for High‐Efficiency Solar Cells

open access: yesSmall, EarlyView.
Direct injection synthesis with short‐chain decylammonium iodide produces uniform FAPbI3 perovskite nanocubes through isotropic growth and surface passivation. The resulting films show reduced defect‐mediated recombination, improved phase stability, and efficient charge transport.

Fast and Selective Photochemical Doping of Spiro‐OMeTAD

open access: yesSmall Methods, EarlyView.
Sixty seconds of UV light converts spiro‐OMeTAD into its clean +1/+2 oxidized states while >98% of lithium is extracted into an aqueous phase by 12‐crown‐4. Proton‐tunable hydroxyl‐radical chemistry generates oxidants whose reduction potentials bracket the spiro2+/spiro3+ couple, providing thermodynamic oxidation‐state selectivity, as quantified by DFT.
