Maximize production efficiencies

From raw material testing, process monitoring, failure analysis, and QA testing.

Application Note

Copper Indium Gallium Selenide (CIGS) is a direct bandgap semiconductor used in the manufacturing of solar cells. Because CIGS strongly absorbs sunlight, less material is required than for other semiconductor materials and this has led to the production of improved photovoltaics. Energy-Dispersive X-ray Fluorescence (EDXRF) as a truly nondestructive technique is ideal for the characterization of CIGS solar cells, to determine both layer composition and thickness.
