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.

PTAA or Spiro-OMeTAD? | Choosing a HTL for your Solar Cells

PTAA and Spiro-OMeTAD are both used as hole transport layers in high efficiency perovskite solar cells (PSCs). Regular architecture devices using PTAA and Spiro-OMeTAD layers have demonstrated power conversion efficiencies (PCEs) of over 22% and 25% respectively.
