Alkali relationship to n-type defects. (a) Alkali segregation is compared to \({\rm{\Delta }}{({\rm{In}}+{\rm{Ga}})}_{BI}\). A positive slope may indicate a correlation of alkali incorporation to a reduction of the n-type defect (In, Ga)Cu. However, no clear relationship is measured. (b) Alkali incorporation is compared to \({{\rm{\Delta }}\text{Se}}_{BI}\). A negative slope may indicate a correlation of alkali segregation to a reduction of the n-type defect VSe. Again, no clear relationship is measured.
