This study presents a new methodology for identifying environmentally friendly solvents for inverted structure quantum dot light-emitting diodes (QD-LEDs) hole transport layers (HTL), using Hansen solubility parameters (HSPs) and solvent selection guidelines (SSGs). We discovered a green solvent that enhances processability and device performance with a clear interface.
