a) Schematic illustration of the inverted OSC with a hybrid PEG–TiOx CIL. b) Molecule structures of PDTTBT‐3, PTB7, PTB7‐Th and PC71BM. c) Energy levels of each component used in the OSCs. d) WFs of ITO, TiOx and PEG–TiOx films determined by a Kelvin probe technique. Improved device performance of different polymer‐based OSCs using the PEG–TiOx CIL: e) J–V characteristics under AM 1.5G irradiation (100 mW cm−2), and f) Device stability of the OSCs.
