Interfacial engineering has proven effective in enabling improvements in the performances in optoelectronic devices. In particular, self-assembled monolayer (SAM) as a hole selective contact has led to more than 21% in power conversion efficiency. Herein, we reported the synthesis and characterization of phenothiazine-based hole transport materials for inverted perovskite solar cell. In this study, we developed novel phenothiazine derivatives which have well aligned frontier molecular orbital energy levels for hole extraction and electron blocking. This material has shown improved the power conversion efficiency up to 22.4%.
