Self-Assembled Monolayer as a Hole-Transport Layer Forming a Robust Interface with the Active Layer for Enhanced Thermal Stability in Organic Solar Cells

Abstract

Can self-assembled monolayer (SAM)-based hole transport layers (HTLs) overcome the interfacial instability issues associated with PEDOT:PSS and offer a more robust platform for charge extraction, both mechanically and electrically? This work provides a rationale for the improved thermal and interfacial stability of the SAM HTL in organic solar cells.
