SectorInspector for microscopic inspection
Microscopic exposure of a laser rill on a polycrystalline solar cell
But now we expanded its high resolution inspection to near infrared (900-1700 nm) for the use with photovoltaic modules, allowing a fast macroscopic prescreening in conjunction with electroluminescence to address interesting areas microscopic afterwards.
Macroscopic NIR exposure
The aim is to deliver a consistent quality control in the manufacturing process of photovoltaic modules. Next to the large area microscopic measurement and analysis of thin film modules this allows now even the inspection of material defects, so called "micro cracks".
Using a motorized InGaAS camera unit and electroluminescence to activate the solar module, faulty cells can be identified without moving the solar module.
Opto and its partners working right now on a solution to generate and analyse high resolution NIR pictures in milliseconds, to be able to integrate such a system into production processes.
