Description
The Potentiostatic—Constant Illumination experiment is used to convert the LED current into light power in watts. This parameter is needed in order to calculate the efficiency of a dye-sensitized solar cell (DSSC).
The MASTER potentiostat controls the LED and applies a constant signal during the experiment. The second potentiostat (SERF) controls a cell (or a photo-diode) and measures its current response. If a photo-diode is used, the measured current can be converted into light power by using responsivity factors which depend on the LED wavelength.
