Copper-gallium planar targets are commonly used in the preparation of copper indium selenide gallium thin-film solar cells and other fields; this dataset includes the main raw materials, auxiliaries, energy, atmospheric emissions, water emissions, and waste from the production process. The manufacturing equipment, construction of production facilities, and other infrastructure are not included within the scope of the dataset boundaries; the data is derived from literature; the production process of copper-gallium planar targets includes vacuum distillation reduction, smelting, casting, hot rolling, hot isostatic pressing, machining, inspection, cleaning, and polishing processes.
