Electron / Hole Transport Layer Materials

We sell a wide range of transport layer semiconducting molecules including:

Electron transport layer (ETL) / hole blocking layer (HBL) materials
Hole transport layer (HTL) / electron blocking layer (EBL) materials
Electron injection layer (EIL) materials
Hole injection layer (HIL) materials

These molecules are suitable for OLED applications and in the fabrication of other organic electronic devices such as OFETs, OPVs and perovskite solar cells (PSCs). Maximize your device efficency by fabricating and testing new devices in a glove box environment.

Self-Assembled Monolayers (SAMs) vs PEDOT:PSS

Two commonly used materials for hole selective layer (HSL) or hole transport layer (HTL) are PEDOT:PSS (poly(3,4-ethylenedioxythiophene) polystyrene sulfonate) and self-assembled monolayers (SAMs). Each offers distinct advantages and limitations that impact their effectiveness in solar cells.
