Figure 4. (A) TPV and (B) TPC for PTzBI-oF:PYF-T-o devices with and without Ti₃C₂ doping in the PEDOT:PSS interlayer; (C and D) Two-dimensional TA color plots, (E and F) TA spectra and (G and H) the trace kinetic of GSB signals of PEDOT:PSS/PTzBI-oF:PYF-T-o and Ti₃C₂:PEDOT:PSS/ PTzBI-oF:PYF-T-o bilayers. TPV: Transient photovoltage; TPC: transient photocurrent; PEDOT:PSS: poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate); TA: transient absorption; GSB: ground state bleaching.
