Determination of selenite in electrolyte solutions for production of CIGS solar cells
Resumo
This Application Note describes the polarographic determination of selenite 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 a molybdenum-coated substrate.
Selenite analysis is carried out after dilution of the sample with sulfuric acid as supporting electrolyte.
