Precise impurity control in raw materials and manufacturing processes increases the quality of solar cells.

The solar grade silicon (SOG-Si) used in solar cells must have carbon and oxygen concentrations of just a few mass ppm or less. Some manufacturing methods use graphite receptacles, so carbon and oxygen concentrations must be strictly analyzed and controlled. Therefore, impurity control is essential in both material and manufacturing processes. HORIBA’s elemental analysis tools provide high-precision, repeatable analyses of carbon, oxygen, hydrogen, and other elements, which are vital to quality control in solar cell manufacturing processes.
