The solar cell as a diode with ADM3

Principle

A solar cell consists of a p-doped and an n-doped layer. When light falls on them, free charge carriers are created, which are forced outwards by the electric field and thus generate a voltage. Due to this structure, the orientation of the voltage is clearly determined, which makes the following experiment possible. In this experiment, a voltage is applied to the darkened solar cell to show in a simple example that the solar cell has the properties of a diode. In an additional partial experiment, the dark characteristic of the solar cell can then be determined.

Benefits

• Part of a system solution - easily expandable for further experiments
• Simple teaching by using the demo board physics
• Clear test execution by using ADM3 multimeters
