Figure 3. Top: Thin-film transmission quartz cell with Pt grid as working electrode, Ag/AgCl as reference electrode and Pt as counter electrode. Bottom: Experimental set-up for absorptovoltammetry. From left to right: Potentiostat with connection to the electrodes and trigger cable for triggering the fibre spectrometer, light source (halogen and deuterium light), quartz cell in the cell holder, fibre spectrometer. Fibre connection via two fibres: Light source - cell - fibre spectrometer.
