Artificial Phototropic Systems for Enhanced Light Harvesting Based on a Liquid Crystal Elastomer
Advanced Intelligent Systems, Volume 3, Issue 10, October 2021., 2021 A versatile, low‐cost, mechanically strong, unconcentrated sunlight‐driven artificial phototropic system is reported. Benefited from double‐leg and bimorph design, it can bear load and achieve large reorientation angle simultaneously. This system is demonstrated to be able to recover the oblique‐incidence‐induced energy‐density loss for photovoltaics ...

Dual‐Color Emission from Monolithic m‐Plane Core–Shell InGaN/GaN Quantum Wells
Advanced Photonics Research, Volume 2, Issue 6, June 2021., 2021 A dual‐color emission is achieved from GaN microwires combining two monolithic core–shell multiple quantum well (MQW) sets. The shell is composed of 3× blue and 7× green m‐plane MQWs with In content measured equal to 15.7% and 23.5% covering 400–450 and 450–550 nm wavelength band emission, respectively. A flexible light‐emitting device integrating dual‐
