Benzotrithiophene‐Based Hole‐Transporting Materials for 18.2 % Perovskite Solar Cells [PDF]

Angewandte Chemie International Edition, 2016
AbstractNew star‐shaped benzotrithiophene (BTT)‐based hole‐transporting materials (HTM) BTT‐1, BTT‐2 and BTT‐3 have been obtained through a facile synthetic route by crosslinking triarylamine‐based donor groups with a benzotrithiophene (BTT) core. The BTT HTMs were tested on solution‐processed lead trihalide perovskite‐based solar cells.
