All‐Solution‐Processed Perovskite Light‐Emitting Transistors Enabled by a Fully Organic Architecture
Fully solution‐processed light‐emitting transistors based on CsPbBr3 perovskite nanocrystals (Pe‐LETs) are demonstrated using an all‐organic platform. By optimizing film formation and device integration, the Pe‐LETs achieve bright green emission with excellent color purity and a peak external quantum efficiency of 4.17 × 10−3 %, marking a step forward ...

A novel carbon dots material (BUL‐CDs) with an initial afterglow brightness (406 cd m−2) far exceeding that of other afterglow luminescent materials was developed. Furthermore, the BUL‐CDs exhibited time‐dependent afterglow colors, excitation‐dependent afterglow colors, and thermochromic afterglow in response to triplet variables.

While perovskite solar cells have been widely studied, including their stability, perovskite indoor photovoltaics (IPVs) have only recently emerged. Nevertheless, more studies are appearing in the literature. The systematic stability study of IPVs is crucial, particularly given the inconsistencies in reported methodologies and results, which call for ...

This study presents a laser‐assisted glass‐frit encapsulation method for perovskite solar cells, comparing air‐, nitrogen‐, and CO2‐filled cavities. Results show that excluding oxygen and moisture significantly improves stability under illumination. The findings reveal the critical role of trapped gases in degradation, providing a pathway to durable ...

Spontaneous Perovskite Passivator Featuring Dual Functional Groups
A novel strategy to suppress multiple defect sites in perovskite crystals using a spontaneous passivator with dual functional groups is proposed, addressing an intrinsic drawback of conventional spontaneous perovskite passivators. 2‐thiophene‐ethyl‐ammonium‐bis(trifluoromethylsulfonyl)imide (TEA‐TFSI) is newly synthesized and successfully demonstrate ...
