Energy level tuning of TPB -based hole-transporting materials for highly efficient perovskite solar cells

Two TPB-based HTMs were synthesized and their energy levels were tuned to match with perovskite by introducing electron-donating groups asymmetrically. The TPBC based doping-free perovskite solar cell afforded an impressive PCE of 13.10% under AM 1.5G ill
