Spiro-OMeTAD (or Spiro-MeOTAD) is one of the most studied and suitable hole transport layer materials due to its facile implementation and high performance in organic-inorganic electronic devices. The spiro-linked molecule provides high glass transition temperature (Tg), morphological stabilit, and easy processability, while maintaining good electronic properties. Widely used in solid-state dye-sensitized solar cells, organic light-emitting diodes, perovskite solar cells, and polymer-based organic solar cells, it is an ideal choice across many areas of research.
