Figure 14.
The graph illustrates the relationship between current, measured in milliampere per square centimetre, on the vertical axis and voltage on the horizontal axis. The vertical axis ranges from 0 to 25 milliampere per square centimetre, while the horizontal axis spans from 0 to 1.2 volts. Five different curves represent four types of C Z T S Z n S samples, C Z T S A D Z n S, C Z T S 340 Z n S, C Z T S 360 Z n S, and C Z T S 380 Z n S, with corresponding markers, solid circles, solid red circles, solid blue triangles, and solid magenta inverted triangles. Each curve shows a decreasing trend in current as voltage increases, dominating the upper to lower range of the graph. The legend in the upper right quadrant identifies the samples with clear symbols and colours.Current plotted against voltage provide from simulation for all CZTS thin films when ZnS was used as buffer layer
