Theoretical determination of the asymmetric interface continuous photogeneration charge transfer rate under bias conditions

Abstract

This paper optimizes the interface charge transfer rate model and combines it with the interface to determine the charge transfer rate under continuous polarization conditions and in non-aqueous systems. The order of magnitude of the net interface charge transfer rate is found to be 10⁻¹⁶ cm⁴/s, which meets the upper limit of the interface charge transfer rate and aligns with the range of different electrolyte ions within the double-layer scale. Compared with previous errors in semiconductor interface charge transfer rates (10³ ~ 10⁴), the magnitude of the error is reduced by 10⁰ ~ 10¹. Additionally, the time scale of the interface charge transfer is determined using the dual-channel method.
