Anion‐Cation Synergistic Passivation for High‐Performance FA‐Cs Halide Perovskite Photodetectors

Advanced Electronic Materials, EarlyView.
An anion‐cation synergistic passivation strategy is developed to improve perovskite photodetectors. Surface‐localized DMePDA2+ cations and bulk‐diffused Cl− anions simultaneously reduce defects, enhancing charge transport and suppressing recombination.

Local Order Is Not Enough: Synthetically Accessible Polymers Reveal the Role of Side‐chain Branching Point in Organic Solar Cell and Transistor Performance

Advanced Electronic Materials, EarlyView.
Systematic variation of the side‐chain branching point in a series of donor polymers reveals that moving the branch further from the backbone improves local crystal quality but reduces the overall degree of crystallinity, leading to progressively worse organic solar cell and transistor performance.

Eco‐Friendly Laser‐Induced Graphene/Perovskite Hybrids for Eco‐Friendly Photodetectors

Advanced Electronic Materials, EarlyView.
A sustainable paper‐based photodetector was developed by combining laser‐induced graphene (LIG) with MAPbI3 perovskite. Compared with pure LIG devices, the hybrid photodetector exhibited nearly 10‐fold higher responsivity and 7‐fold greater detectivity while maintaining stable performance after 1000 bending cycles, demonstrating its potential for ...

High‐Responsivity and Fast‐Response Organic Phototransistor Based on Dinaphtho[2,3‐b:2′,3′‐f]Thieno[3,2‐b]Thiophene

Advanced Electronic Materials, EarlyView.
Low‐temperature Al/Al2O3/DNTT/Au organic phototransistors fabricated on flexible PEN combine high responsivity to blue light (≈250 A W−1 at 39 nW cm−2) with detectable modulated photoresponse up to 150 kHz, making them promising for ultra‐low‐light sensing and moderate‐speed optical links.

High‐Detectivity InGaAs/GaAsP Superlattice PIN Photodetector with a Thin Absorber on GaAs substrate for 1100 nm Applications

Advanced Electronic Materials, EarlyView.
A high‐performance strain‐compensated InGaAs/GaAsP superlattice SWIR photodetector was successfully grown by MOCVD on a scalable 100 mm GaAs platform. Combining excellent structural quality with strong optoelectronic performance, the device delivers a low dark current density of 2.3 × 10−7 A/cm2 and a detectivity of 1.9 × 1011 Jones at 1100 nm ...
