Instability in the exchange of the vacancy of zinc and copper

Youssef Larbah

Dear M. Adnane,

welcome,

The following reasons can play a role for stoechiometry in CZTS:

The initial composition of ions Cu, Sn,Zn and S.

The secondary phase formation such as Cu2-XS in CZTS promotes the non-stoichiometric.
