Above is main testing station for photovoltaic cells and photodetctors. It includes a solar simulator, monochromator, semiconductor parameter analyzer, and lock in amplifier with chopper. Thin film devices are tested inside a nitrogen glovebox (upper) to protect unpackaged cells from oxygen and humidity. The solar simulatior and other optics (lower) feed light into the glovebox from outside.
A second solar simulator is available in our optics laboratory for experiments which require a more extenive suite of analytical tools.
A large capacity oven can hold solar cells at a stable, elevated temperature for lifetime testing.
