Fig. 1: Balance of steady-state photon (I0), interfacial electron transfer (jtr), recombination (jrec), and diffusion-controlled charge (Fq) fluxes.

EVB and ECB are the energetic positions of the valence and conduction band, respectively, EF,p and EF,n are the quasi-Fermi levels of the holes and electrons, respectively, Vph is the semiconductor photovoltage, and Efilm is the electrochemical potential of the MOF film. The molecular structure of the linker is pictured on the right.
