Hole-Transporting Materials for Perovskite Solar Cells Employing an Anthradithiophene Core.

ABSTRACT: A decade after the report of the first efficient perovskite-based solar cell, development of novel hole-transporting materials (HTMs) is still one of the main topics in this research field. Two of the main advance vectors of this topic lie in obtaining materials with enhanced hole-extracting capability and in easing their synthetic cost. The use of anthra[1,9-bc:5,10-b'c']dithiophene (ADT) as a flat π-conjugated frame for bearing arylamine electroactive moieties allows obtaining two novel highly efficient HTMs from very cheap precursors. The solar cells fabricated making use of the mixed composition (FAPbI₃)_0.85(MAPbBr₃)_0.15 perovskite and the novel ADT-based HTMs show power conversion efficiencies up to 17.6% under 1 sun ill
