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