アプリケーション

Spiro-TTB is a high-mobility organic semiconductor with strong donor character given its four substituted arylamine moieties that stabilize positively charged cationic states via mesomeric effects.
It has been successfully applied as transparent hole-transparent layer in solar cells, organic field-effect transistors (OFETs), and organic light emitting devices (OLEDs). In photovoltaics, spiro-TTB was used as organic hole selective layer between perovskite and the silicon cells, contributing to a 25.2% efficency perovskite/ silicon tandem solar cell. When used in OLEDs, spiro-TTB enabled applications in organic photodetectors (OPDs), imaging and lasing applications.

Spiro-TTB is used as a hole transport material in OLED devices, organic photovoltaics (OPVs), organic field-effect transistors (OFETs) and perovskite solar cells. It exhibits excellent hole injection and transport properties, enabling efficient charge transport from the anode to the emitting layers of the OLED structure. This contributes to improved device performance, stability, and overall efficiency.
