"Selectivity losses correspond to a drop between the internal and external voltages of the cell. Internal voltage is a measure of how defects within the bulk of the absorber and at its interfaces reduce voltage below an ideal thermodynamic limit. External voltage corresponds to internal voltage minus losses due to non-ideal behavior in the semipermeable membranes that sandwich or wrap the cell absorber and direct the electron flow in and out of the cell to generate an electric current"
