The Cover Feature illustrates surface‐sensitive probing of a molecularly functionalized model photoelectrode with vibrational sum frequency generation (VSFG) spectroscopy. VSFG spectroscopy unravels the effect of the surface roughness on the adsorption and assembly of the dye molecules. The VSFG signal (ω1+ ω2) originating from the dye‐sensitized surface encodes physical information about the resonant interaction of the incident visible (ω1) and mid‐IR (ω2) photons with the molecules at the interface.
