Recently, silicon has attracted attention as not only the semiconductor but also as a material for the solar cells. It is known that impurities such as oxygen and the carbon exist in silicon, and there impurities are known to affect its electrical properties. So it is important to control its concentration in low concentration level. Oxygen/ Nitrogen analyzer EMGA series and Carbon/Sulfur analyzer EMIA series has been recognized as a measuring device capable of rapid and accurate in low level of time, and various application developments have been also done in the long history. In this study, we introduce new measurement application of oxygen and carbon in silicon for solar cells as an example of the application.
