Application

ITIC-F can be employed as the electron transport layer (ETL) in OFET devices. It can be blended with donor polymers to form the active layer in p-type OFETs. ITIC-F exhibits a broad absorption spectrum that extends into the visible and near-infrared regions. This characteristic allows for effective light absorption across a wide range of wavelengths and contributes to enhanced light-harvesting and power conversion efficiency in OPV devices. ITIC-F is commonly used as a non-fullerene acceptor in OPV devices. It serves as the electron acceptor material alongside a donor polymer in the photoactive layer.
ITIC-F is a derivative of ITIC possessing lower energy levels and a broader absorption spectrum. It is used as an n-type molecule for organic photovoltaics, allowing very high performances of over 13%.
ITIC-F is a non-fullerene acceptor molecule, which can be used in the fabrication of organic solar cells (OSCs) and organic photovoltaics (OPVs).
