General description

TPBi is an organic semiconductor that displays high electron mobility (3.3×10−5 cm2 V−1 s−1) and high glass transition temperature. It is widely used as an electron transport layer(ETL) in QLEDs and OLEDs, which is a cathode buffer layer in organic solar cells.

The increase in power conversion efficiency of the device on the addition of TBPi is attributed to the following reasons:
  • Preventing exciton from quenching at the acceptor/cathode interface.
  • Acting as an optical spacer.
  • Forming a passivating layer.

Application

TPBi can be used to fabricate an electron transport layer for organic-inorganic hybrid perovskite LEDs.
