Ferrocene‐Based Self‐Assembled Monolayers Enable Ultra‐High Specific Detectivity in Perovskite Photodetectors

open access: yesAdvanced Materials, EarlyView.
We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Molecular N‐Type Doping Enables Schottky Interface Engineering in HTL‐Free Self‐Powered Perovskite Photodetectors: From Visible to Near‐Infrared Detection

open access: yesAdvanced Optical Materials, EarlyView.
N‐DMBI doping enhances interfacial band bending to suppress charge injection, while tin incorporation extends the spectral response toward the near‐infrared, enabling broadband perovskite photodetectors with high detectivity. ABSTRACT Hole‐transport‐layer‐free perovskite photodetectors offer a simplified architecture for self‐powered optoelectronics ...

Engineering Slow‐Carrier Interfacial Recombination Enables Tailored Spectral Response

open access: yesAdvanced Science, EarlyView.
This work demonstrates that weak‐drift slow carriers are preferentially captured at generic semiconductor surfaces/interfaces and recombine. This process is manipulated to achieve tailored spectral response. A tens of µm‐wide depletion region is created to observe surface collection rates for photocarriers generated at different positions.

Synergistic Additive and Bulky Cation Engineering via a Sequential Vacuum Dry‐Dipping Process for Tin Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
A spin‐coating‐free sequential blade–dipping process is developed for efficient tin perovskite solar cells. Amorphous SnI2 templates are blade‐coated and vacuum‐dried, followed by a vertical dipping conversion. Enhanced by a synergistic additive matrix and bifunctional BATo cation, the resulting devices achieve a benchmark power conversion efficiency ...
