Amplifying Electron Sink Effect and Piezoelectric Polarization in Size-Minimized Nitrogen-Rich Carbon Nitride Nanosheets for Boosting H2O2 Piezo-Photosynthesis under Pure Water

Abstract Piezo-photocatalysis offers a promising technology for H2O2 production, yet its practicability is limited by insufficient charge separation, inert reaction sites, and inadequate polarization fields. Herein, we present a size-minimized nitrogen-rich carbon nitride, engine...

Graphene‐Engineered Rear Interfaces Enable Efficient Flexible CZTSSe Solar Cells on Metal Foils

ABSTRACT Flexible kesterite (S,Se) (CZTSSe) solar cells on metal foils are attractive for lightweight and conformable photovoltaic applications, yet their efficiencies remain significantly lower than those of rigid devices due to severe foil‐induced rear‐interface losses during h...
