Multiport photo-electrochemical single-sided cell setup
This is a horizontally mounted, single compartment multiport photo-electrochemical cell. This cell allows several approaches to perform measurements in 2- or 3-electrode setups. It is designed to investigate performance of a thin film photo-anode (e.g. nanocrystalline material or conducting polymer) deposited on a rigid or flexible transparent substrate (typically fused quartz glass). The cathode (counter electrode) and reference electrode are typically mounted in a top lid, while both side lids can be used to mount up to 4 additional electrodes (e.g. pH meter, thermometer, Clark electrode, etc.). The tubing installed in side lids enables aliquot sample collection (liquid) and supply of gaseous and liquid reagents. The gas inlet and outlet in the top lid can be used to bubble the solution and evacuate gases from the chamber. It well fits aqueous (FKM/EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight.
A thin film of interest (photo-anode) deposited on a transparent glass or plastic foil is installed in the magnetic/screw mount, facing the cell chamber. In 2-electrode setup, the counter electrode is placed in the socket close to the working electrode while the remaining socket is plugged. When 3-electrode setup is required, the reference electrode is placed close to the measured sample to limit the effect of electrolyte resistance, while the counter electrode occupies the remaining socket. Various auxiliary electrodes are suitable for this cell including metal wire, gauze and foil electrodes as well as non-metal electrodes. Typical applications include: basic photochemistry, photolytic water splitting, photoinduced charge separation and photocorrosion.
