Recent Research Progress in Surface Ligand Exchange of PbS Quantum Dots for Solar Cell Application

Recent Research Progress in Surface Ligand Exchange of PbS Quantum Dots for Solar Cell Application

Colloidal quantum dots (CQDs) are considered as next-generation semiconductors owing to their tunable optical and electrical properties depending on their particle size and shape. The characteristics of CQDs are mainly governed by their surface chemistry, and the ligand exchange process plays a cruc...

The characteristics of CQDs are mainly governed by their surface chemistry, and the ligand exchange process plays a crucial role in determining their surface states.
