A swivel-cruciform thiophene based hole-transporting material for efficient perovskite solar cells

A novel swivel- cruciform 3,3'- bithiophene based hole- transporting material (HTM) with a low lying highest occupied molecular orbital (HOMO) level was synthesized. This new HTM (KTM3) in CH3NH3PbI3 perovskite solar cells showed a higher V-oc (1.08 V) and fill factor (78.3%) compared to solar cells fabricated using the widely used spiro-OMeTAD.
