Bio-inspired Water-Free Synthesis of Amino Acid-incorporated MAPbBr3 hybrid Perovskites: Correlating Lattice strains to Optical Properties
收藏资源简介:
Our research draws inspiration from biogenic calcite's ability to incorporate biomacromolecules. Through ESRF experiments, we demonstrated the incorporation of amino acids (AAs) into various materials, including methylammonium lead bromide perovskites (MAPbBr3), widening their band gap and improving humidity stability critical for solar cells. Herein, we propose investigating for the first time water-free AA incorporation into MAPbBr3. Our focus is understanding how growth kinetics influence AA incorporation and their impact on crystal structure and optical properties. We'll grow MAPbBr3 crystals in non-water environments with 10 AAs, characterizing their structure via HR-PXRD on ID22. Additionally, we'll analyze the correlation between AA concentration and induced lattice distortions, linking them to changes in optical band gap. We believe this research will pave the way for bio-inspired enhancements in optoelectronic materials.
