Application

EH-IDTBR is a branched non-fullerene acceptor (NFAs) used in organic photovoltaic (OPV) devices. It is used along with donor polymer, poly (3-hexylthiophene) (P3HT) to fabricate the solar cells to enhance the power conversion efficiencies and stabilities of the devices. It is also used to develop n-type small molecules for organic thin-film transistors (OTFTs) because of their n-type electron mobility.

Solution-processed organic photovoltaics (OPV) offer the attractive prospect of low-cost, light-weight and environmentally benign solar energy production. The highest efficiency OPV at present use low-bandgap donor polymers, many of which suffer from problems with stability and synthetic scalability. They also
