Trace MA+ Accelerates the Degradation of Perovskite Solar Cells at Elevated Temperatures

open access: yesInformation &Functional Materials, EarlyView.
We investigate how the A‐site cation influences the morphology and optoelectronic properties of perovskite films, and consequently, the operational stability of devices under continuous light illumination at elevated temperature. ABSTRACT Methylammonium (MA+) is the most widely adopted A‐site cation for high‐efficiency perovskite solar cells.

Core‐shell structure induced surface reconstruction of PbS quantum dots toward high‐detectivity short‐wave infrared photodetectors

open access: yesInfoScience, EarlyView.
We present a core‐shell structure‐induced surface reconstruction treatment for PbS quantum dots (QDs). Highly detective photodetectors and imagers in the short‐wave infrared region are demonstrated based on the surface‐reconstructed QDs with reduced dark current density and improved QD stacking configuration, as shown by grazing‐incidence small‐angle X‐

Perovskite‐based time‐domain signal‐balancing LiDAR sensor with centimeter depth resolution

open access: yesInfoMat, EarlyView.
In this study, we present a monolithic high‐speed perovskite‐based photodetector capable of directly sensing the time delay between two light pulses with a temporal resolution of at least 170 ps. This outstanding time resolution is achieved through a signal‐balancing detection scheme that effectively overcomes the limitations of conventional ...

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials

open access: yesLaser &Photonics Reviews, EarlyView.
This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...
