Popis

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 due to its broad energy band and superior electron transport properties. It also serves as an excellent host material for both fluorescent and phosphorescent LEDs because of its optical, electronic, and processing characteristics.
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.
