General description
Spiro[9H-fluorene-9,9′-[9H]xanthene]-2,7-diamine (X59) is a hole transporting material (HTM), which has a spiro[fluorene-9,9′-xanthene] as a core component. It can be synthesized by Buchwald-Hartwig reaction. It shows a power conversion efficiency (PCE) of 19.8%.
Application
X59 can be used in the formation of hole transporting layer (HTL) for the fabrication of polymeric solar cells (PSCs) and perovskite solar cells.
X59 is a new hole transporting material (HTM) with spiro[fluorene-9,9′-xanthene] as the core moiety. An impressive power conversion efficiency (PCE) of 19.8% was achieved by using X59 as HTM in perovskite solar cell, which can compete with the record PCE by using the state-of-the-art-HTM Spiro-OMeTAD. The X59-based devices show negligible hysteresis and reasonable stability in dark and dry conditions at room temperature for over five weeks.
