Exciplex-Facilitated Charge Extraction and Defect Chelation to Improve Inorganic Perovskite Solar Cells

Abstract Rational molecular engineering of the perovskite/hole transport layer interface offers a promising route to simultaneously address inefficient charge extraction, defect-mediated recombination, and lead leakage in CsPbI3–xBrx perovskite solar cells. Herein, we introduce 2...

Interfacially Assembled Hollow AuAg Nanostars on Flexible PDMS for Sensitive SERS Detection

Optimizing the morphology and structure of noble metal nanomaterials is critical for the design of high-performance surface-enhanced Raman scattering (SERS) substrates for trace analyte detection. A plasmon-tunable SERS platform consisting of AuAg alloy nanostars anchored on a hy...
