Self-assembled organic molecules with a fused aromatic ring as hole-transport layers for inverted perovskite solar cells: the effect of linkers on performance

Abstract

Two D–π–A structured SAMs (FNE29 and DT-1) with different linkers are self-assembled onto the indium tin oxide (ITO) substrates as HTLs for inverted PSCs. The results indicate that the SAMs with large conjugated fused linkers have obvious advantages as HTLs because of its fast hole transfer.
