Solar cell analysis system
Monochromatic light spot size
The light spot size can be varied by software in various steps between a homogeneous 20 x 20 mm² square and a point of 1 x 3 mm².
Change-over between EQE and REFL
The integrating sphere is motorized and inserted in the optical path such that both reflectance and EQE are measured with exactly the same monochromatic light beam.
