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