Description
Spiro-OMeTAD (Spiro-MeOTAD) is one of the most studied and suitable hole transport layer materials (HTL) due to its facile implementation and high performance in organic-inorganic electronic devices. The spiro-linked molecule provides high glass transition temperature (Tg), morphological stability and easy processability while maintaining good electronic properties. Spiro-MeOTAD has been widely used in solid-state dye-sensitised solar cells (ssDSSC), organic light-emitting dioes (OLED), perovskite solar cells (PSCs) and polymer based organic solar cells (OSCs).
Odor White to pale yellow powder
