Description

General description

Spiro[9H-fluorene-9,9′-[9H]xanthene]-2,2′,7,7′-tetramine (X60) is a hole transporting material (HTM) with a nonplanar 3D structure which reduces the electronic coupling and charge recombination. It can be used as a starting material in the fabrication of green and cost effective p-type organic semiconductors.

X60 is cheaper alternative to Spiro-OMeTAD.
X60 is a spiro[fluorene-9,9′-xanthene] (SFX) based organic hole transport material (HTM).
Devices with X60 as HTM showed high power conversion efficiencies (PCEs) amounting to 7.30% in solid-state dye-sensitized solar cells (ssDSCs) and 19.84% in perovskite solar cells (PSCs). These results are competitive with the reported record PCEs of ssDSC and PSC devices based on the well-known HTM Spiro-OMeTAD. In addition, almost no hysteretic behavior could be observed in the X60-based PSCs, and the photovoltaic parameters of the devices are not affected by the scan rates used.

Application

X60 can be used as a conducting polymer in the formation of perovskite based solar cells with high efficiency.
