Overview | Specifications |Pricing and Options | Literature and Reviews
Spiro-OMeTAD (or Spiro-MeOTAD), CAS number 207739-72-8, 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 diodes (OLED), perovskite solar cells (PSCs) and polymer based organic solar cells (OSCs).
Spiro-OMeTAD (Spiro-MeOTAD) from Ossila was used in the high-impact paper (IF 29.37), Interfacing Pristine C60 onto TiO2 for Viable Flexibility in Perovskite Solar Cells by a Low-Temperature All-Solution Process, Y. Zhou et al., Adv. Energy Mater., 1800399 (2018); DOI: 10.1002/aenm.201800399; and paper (IF 39.714), In situ simultaneous photovoltaic and structural evolution of perovskite solar cells during film formation, M. Alsari et al., Energy Environ. Sci., 11, 383-393 (2018); DOI: 10.1039/C7EE03013D.
