This is an entry level setup for photoelectrochemistry. It consists of a potentiostat, a LED revolver, a universal electrochemical cell and a set of electrodes: reference Ag/AgCl and platinum counter electrode.
The device is ready for two and three electrode measurements.
The LED revolver delivers irradiation from 10 LEDs in UV, Vis and NIR range.
Although this is a budget version of a full photoelectric spectrometer, it is rich in measurement possibilities.
Currents can be measured as a function of external potential, illumination wavelength or intensity. Open Circuit Potential determination of a sample under illumination is also provided.
Mini photoelectric spectrometer can measure electric currents from 10 mA to 1 pA with a single pA resolution.
LED revolver automatically selects one of the 10 mounted LEDs.
One can perform current measurements when potential and light intensity are scanned across set ranges.
A sample is placed in a PTFE electrochemical cell that handles both transparent and opaque substrates.
The Kelvin probe system allows precise measurement of work function of different semiconducting and conducting materials with high precision and accuracy
