Recent Advances in Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Sustainable 4D Printed Meta Biocomposite Materials for Programmable Structural Shape Changing

open access: yesAdvanced Materials, EarlyView.
In this work, the architecture of a plant fiber cell wall is simplified to design novel concepts of 4D printed tubular moisture‐driven structural actuators, using the hygromorphic properties of continuous flax fiber (cFF) reinforced materials named meta biocomposites.
