C60 Pyrrolidine tris-acid

Description

• General description: C60 Pyrrolidine tris-acid (CPTA) is a fullerene derivative that has carboxyl functionalized carbon buckyballs. It is majorly used in electrochemical devices as an electron transporting layer (ETL) due to its high energy level and electron mobility. It can be used as an alternative to conventional metal oxide based charge carrying films, through the esterification of a carboxylic acid with hydroxyl groups. Its solubility in water and other polar solvents makes it useful in solution processed devices.[1][2][3]
• Application: C60 Pyrrolidine tris-acid may be used as a cathode buffer layer in solar cells.[1] It may be used as a wetting layer in an organic photovoltaics.[5]
