Solar cell analysis system

Quantum efficiency mapping

This method uses the focussed light spot from the monochromator to create maps of EQE and/or REFL at any wavelength between 280 nm and 1200 nm with a spatial resolution of approximately 1 mm. The EQE map at 1000 nm of a 156 x 156 mm² solar cell on the right was taken in 5 minutes.
