Read the characteristics in order. The first is the ordinary forward-and-reverse curve of a simple diode; the second adds a sharp reverse breakdown, the signature of a Zener diode; the third shows an output voltage appearing with no applied bias, which marks a solar cell; the last shows resistance changing with illumination, which is a light-dependent resistor. In order, the devices are a simple diode, a Zener diode, a solar cell and a light-dependent resistor.
