Shedding light on the birth of hybrid perovskites: a correlative study by in situ electron microscopy and synchrotron-based x-ray scattering

By

An additional Friday publication update! Lead halide perovskites (LHPs) are the future of optoelectronic devices, thanks to their unique physical properties. Yet, the synthesis of MAPI perovskites via ligand-assisted reprecipitation (LARP) has so far not been researched. In this groundbreaking study, advanced in-situ techniques were done with the #PoseidonAX and the #Atmosphere system to demystify … Read More
