Balancing Shading and Resistive Losses: 33% Efficient Perovskite/Silicon Tandem Solar Cells via Front‐Electrode Engineering

Advanced Science, EarlyView.
Front‐electrode co‐optimization combining tungsten‐doped indium oxide (IWO) transparent electrode and simulation‐guided metal grid geometry boosts perovskite/silicon tandem solar cell performance. The low work function IWO improves interfacial carrier extraction, while tailored grid parameters balance optical shading and electrical resistive losses ...

Porcupine‐Quill‐Inspired Shape‐Morphing Biointerfaces Disassemble Biofilms

Advanced Science, EarlyView.
A porcupine‐spine‐inspired dynamic offensive bio‐interface is developed for active biofilm disassembly. By coupling electrically driven nano‐dagger penetration with light‐triggered ROS generation, the surface overcomes the passive limitations of conventional mechano‐bactericidal topographies, achieving near‐complete biofilm eradication, strong ...
