Figure 11.
The graph features a plot of electrical current measured in milliamperes on the vertical axis, ranging from 0 to 15, and voltage measured in volts on the horizontal axis, ranging from 0 to 1. Two sets of data points are displayed, dark current represented by black circles and light current represented by red circles. The dark current shows little variation with increasing voltage, while the light current demonstrates significant increases beyond a certain voltage threshold. The graph illustrates the differences in current response under light and dark conditions.I–V characteristic in the dark and illumination of CZTS thin films deposited with sol-gel spin-coating on IFO substrate
