Contact‐Architecture‐Dependent Mixed Ionic‐Electronic Transport in Solution‐Grown MAPbBr3 Microwire Photodetectors

Advanced Optical Materials, EarlyView.
MAPbBr3 microwire photodetectors reveal a strong architecture dependence of mixed ionic–electronic phototransport. A single‐gap device exhibits pronounced illumination‐history‐dependent transients governed by trap‐assisted injection and ionic polarization, whereas a multi‐gap configuration averages local interfacial effects and yields stable ...

Spectral Splitting Using Luminescent Solar Concentrator Lightguides

Advanced Optical Materials, EarlyView.
Attaching selective reflectors to the edges of a luminescent solar concentrator containing two different fluorescent dyes makes it possible to parse the incident white light spectrum into two separate edge emission wavelengths. Separation may be enhanced by aligning the dichroic dyes on the lightguide surface.

Photoactive and Ultrastable Silicon/Boron Doped Diamond Photoanodes Enable Longstanding Photoinduced Electrochemiluminescence

Advanced Optical Materials, EarlyView.
This study introduces a highly durable n‐Si/BDD photoanode for photoinduced electrochemiluminescence that entirely circumvents conventional interfacial passivation. By delivering a stable photovoltage under near‐infrared irradiation, the heterojunction facilitates low‐potential optical upconversion.

Hyperuniform Disorder in Photonic Crystal Slabs With Intrinsic Non‐Hermiticity

Advanced Optical Materials, EarlyView.
Light propagation in photonic crystal slabs with imposed hyperuniform disorder is investigated theoretically and numerically. The hyperuniform disorder is imposed by varying the hole size. The photonic crystal is intrinsically non‐Hermitian due to radiative loss, with non‐Hermiticity appearing as a complex effective mass of a quadratic photonic band ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

Advanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.
