  • Qu et al. report a self-assembled material with π-expanded conjugation to form hydrophilic ordered bilayer as hole selective layer for inverted perovskite solar cells. The enhanced interfacial charge extraction and transport enable certified efficiency of 26.39% and 25.21% for 7.15 mm2 - and 99.12 mm2 -devices, respectively.

  • Achieving a balance between molecular packing density, charge transport efficiency, and defect passivation remains a challenge for perovskite solar cells. Here, authors synthesize self-assembled molecules with flexible head groups and rigid linkers, achieving maximum device efficiency of over 26%.
