Description
- General description: We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product belongs to enabling category of greener alternatives, and has been enhanced for energy efficiency. Click here for more information.
- Application: 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[1]. It has been successfully applied as transparent hole-transparent layer in solar cells[2][3], organic field-effect transistors (OFETs)[4][5][6], and organic light emitting devices (OLEDs)[1]. 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[3]. When used in OLEDs, spiro-TTB enabled applications in organic photodetectors (OPDs)[4], imaging[5][7] and lasing applications[6].
