Maciejczyk, Michal published the artcileSFX as a low-cost ‘Spiro’ hole-transport material for efficient perovskite solar cells, SDS of cas: 159-62-6, the publication is Journal of Materials Chemistry A: Materials for Energy and Sustainability (2016), 4(13), 4855-4863, database is CAplus.
Four spiro[fluorene-9,9′-xanthene] (SFX) derivatives, SFX-TAD, SFX-TCz, SFX-TPTZ and SFX-MeOTAD have been synthesized for use as hole-transport materials and fully characterized by 1H/13C NMR spectroscopy, mass spectrometry, XRD and DSC. Their thermal, optical and electrochem. properties were investigated. The use of different substituents affects the HOMO (HOMO) energy level proving the versatility of the central core towards the facile and low-cost preparation of spiro-hole-transport materials. Among the synthesized SFX derivatives, SFX-MeOTAD was employed as hole-transporting material (HTM) and the performance tested in perovskite solar cells with device architecture glass/FTO/compact TiO2/mesoporous Al2O3/CH3NH3PbI3-xClx/HTM/Au. SFX-MeOTAD gave a comparable efficiency to spiro-MeOTAD, demonstrating great potential for use of the SFX family as cost effective and versatile hole conductors facilitating commercialization of perovskite solar cells (PSCs).
