Determination of copper in electrolyte solutions for production of CIGS solar cells
概要
This Application Note describes the polarograhic determination of copper in electroplating baths used in the production of thin-film copper indium gallium diselenide solar cells (CIGS cells). The CIGS absorber layer is electrodeposited on a molybdenum-coated substrate.
Copper analysis is carried out after dilution of the sample with sulfuric acid as supporting electrolyte.
