The impurities present in silicon for solar cells directly influence its electrical characteristics and therefore solar cells performance. Light non-doping impurities like oxygen, carbon, hydrogen, and nitrogen are of particular importance since they exhibit both a positive and a negative impact when present in silicon substrates. In this overview we illustrate the positive and negative effects of impurities on silicon material properties. It is also shown that their contemporary presence leads to a mutual interaction and hence to the formation of more complex structures.

Abstract
The impurities present in silicon for solar cells directly influence its electrical characteristics and therefore solar cells performance. Light non-doping impurities like oxygen, carbon, hydrogen, and nitrogen are of particular importance since they exhibit both a positive and a negative impact when present in silicon substrates. In this overview we illustrate the positive and negative effects of impurities on silicon material properties. It is also shown that their contemporary presence leads to a mutual interaction and hence to the formation of more complex structures.
