Properties of solar cells - dependence on the illuminance

Principle

Solar cells play a substantial role in the development of alternative, non-fossil sources of energy. They convert light energy directly into electrical energy. 

In this experiment, the influence of the illumination on the short-circuit current and the open-circuit voltage is examined. The illumination can be changed by altering the distance between the solar cell and the light source or by varying the angle of incident light.

Benefits

• No additional cable connections between the building blocks needed - clear arragned and quick setup
• Contact saftey due to puzzle blocks system
• Corrosion-free gold plated contacts
• Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside

Tasks

How does the illumination influence the behaviour of the solar cell?

Examine the influence of the illumination on the short-circuit current and the open-circuit voltage of a solar cell.
