SINTEF, in collaboration with NTNU, operates extensive characterisation laboratories dedicated to materialcharacterisation in general and solar cell silicon in particular.

Sample preparation

We have in-house laboratories dedicated for sample preparation, such as cutting, grinding, mechanical- and chemical polishing of wafers and other samples. Our state of the art etching facilities includes two etch benches
dedicated for silicon etching with automatic filling and careful temperature control for chemical polishing, defect etching and texturisation as well as dissolution of silicon matrix to study inclusions.
