Table 1 Composition of WZ- and ZB-structured CIGS NPs (calculated by the measured atomic ratios derived from EDS, the listed ratios are the average of 6 measured values from three individual samples)
Sample | Cu:In:Ga:S | Cu:(In+Ga) | [0.5Cu+1.5(In+Ga)]:S |
---|---|---|---|
WZ-CIGS | 1:0.86:0.30:2.16 | 1:1.16 | 1:0.96 |
ZB-CIGS | 1:0.68:0.28:1.76 | 1:0.96 | 1:0.91 |
