High-Performance Near-Infrared Perovskite Single-Crystal Photodetectors Enabled by Multifunctional Additive Engineering for Image Encryption

Abstract Iodide-based metal halide perovskite single crystals are promising candidates for near-infrared photodetection because of their favorable bandgaps and outstanding optoelectronic characteristics. However, iodide oxidation during crystallization deteriorates precursor stab...

Chiral Phosphoserine Reconfigures the Energy Conversion Pathway for Efficient and Stable Sequentially Deposited Perovskite Solar Cells

ABSTRACT FAPbI 3 perovskite solar cells (PSCs) fabricated via sequential deposition hold great promise for high photovoltaic performance. However, two bottlenecks remain persistent: transport‐limited conversion that leaves residual PbI 2 and the high thermal prerequisite to drive...

Self-Assembling Hole-Transport Molecules Enable Photomultiplication-Type Organic Photodetectors with High Detectivity and Enhanced Environmental Stability

Photomultiplication-type organic photodetectors (PM-OPDs) have attracted significant attention for their high gain and simplified device architecture. However, their practical application is severely constrained by the high dark current density inherent to charge injection-type m...
