Metrohm Autolab introduces the LED Driver and optical bench for the characterization of photovoltaic devices, like dye sensitized solar cells. The LED Driver is a software programmable controller which can be connected to the Autolab to control the output of the LED light source. The output of the light source can be set to the constant value or can be modulated using the FRA32M impedance analyzer module. Three application notes are available (Part 1, Part 2 and Part 3).
The LED Driver is controlled through the powerful NOVA software.
