应用

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.
