Self-collation of perovskite nanocrystals into superstructures larger length scales has been growing in research interest due to their dramatically enhanced performance various nano-devices, modulating optical and electrical traits. Herein, the unique concentration-dependent self-assembly phenethylamine (PEA)-capped CsPbBr3 (PCPB) perovskites spanning a size range nano micron level without structural phase alteration is infered. By optimizing synthetic parameters like PEA amount, solvents, self-coalescence PCPB crystal growth controlled. Furthermore, highest-concentrated (C5) improved charge transfer (CT) efficiency 1,4-Napthoquinone (NPQ), corroborated with stronger binding between C5 NPQ, compared lowest-concentrated (C1). Incorporating NPQ such enhances local conductance unveiling CT-induced current rise, while detrimental insulating property molecules reduces C1. These outcomes offer foundation for tailoring properties self-assembled optoelectronic devices energy conversion technologies.
