Fig. 4: Charge carrier kinetics and illustrations.
a Hole transfer kinetics from PP-TAS of PA and SMA systems fitting by tri-exponential function, where \({\tau }_{n}\) present the time constant of two interfaces and diffusion-limited transfer, and An are the weight coefficient for each term. b The ratio of A1 and A2 for two systems. c Bound CTEs separation kinetics from PPP-TAS at representative EA response wavelength for PA and SMA system. d Illustration of the dual charge generation pathways originating from the E-and P-interfaces, highlighting their distinct population ratios and charge transfer time. Gray shaded shape on (a) represents the laser pulse width of transient absorption experiments showing the high time resolution here.
