In‐situ photoinduced threshold voltage measurement is a sensitive probe for exploring charge transport and exciton diffusion simultaneously, the main determinants of the power conversion efficiency in organic photovoltaic devices. The exciton diffusion length in a pentacene film deposited onto a C 60 ‐terminated self‐assembled monolayer is measured. The methodology and analysis presented here can be applied in the design and engineering of electron/donor acceptor interfaces for photovoltaic devices..
