Glass and PTFE Photoelectrochemical Cells (PECs)
Electrochemical cells for two or three electrode photoelectric effect studies
Our two or three electrode photoelectrochemical cells, designed for photoelectric effect studies, are available with either a glass or polytetrafluoroethylene (PTFE) body. Both types can employ either a two or three-electrode system using a working electrode, a counter electrode and, optionally, a reference electrode.
The PFFE photoelectrochemical cell features an optical window to collect light onto the working electrode.
Photoelectrochemical cells (PECs) are solar cells based on a semiconductor–electrolyte interface. The working electrode, also referred to as photoanode, is normally an n- or p-type semiconductor, i.e. a polymer semiconductor on an ITO/FTO substrate, held by a platinum sheet working electrode holder. In photoelectrochemical cells, the counter electrode can be platinum or platinum free, i.e. multi-walled carbon nanotubes (MWCNT).

What is a Photoelectrochemical Cell?
A photoelectrochemical cell (PEC) is a type of device that utilises a light source onto a semiconductor or photosensitizer to produce electrical energy (similar to a dye-sensitized solar cell) or to trigger chemical reactions to store energy in the form of chemical bonds, i.e. the production of the hydrogen by the splitting of water.
Photoelectrochemical cells are made up of an electrolyte and either two or three electrodes with an anode, a cathode and/or a reference electrode.
How does a PEC work?
The critical component of the photoelectrochemical cell is the semiconductor, or rather the photosensitizer, on the working electrode. Electron-hole pairs are generated on the working electrode by the irradiation of the photons with an energy level that is equal or greater than the bandgap (Eg) of the semiconductor. When light illuminates the photoanode, electrons on the valence band (VB) get excited to the conduction band (CB), and leave a hole behind.
The photogenerated electrons are swept toward the conducting back contact, and are transported to the metal counter-electrode via an external wire. The electrical energy produced and stored in this process is similar to the a photovoltaic dye-sensitized solar cell (DSSC).
Both these excited electrons and the holes left behind in the photoelectrodes will be involved in some form chemical reactions, i.e. water splitting. At the counter electrode, the electrons reduce protons (H+) to form hydrogen (H2) while the photogenerated holes at the photoanode oxidise water (or OH-) to form oxygen (O2).
Photoelectrochemical cells are light or solar energy driven and they offer a promising potential applications in clean energy captivation, energy production and storage and light-emitting devices.
