Principle

Solar cells play an important role in the development of alternative, non-fossil energy sources. They convert light energy directly into electric energy.
This experiment examines the influence of the intensity of illumination an the open circuit voltage and the short-circuit current. The intensity of illumination can be varied by changing the distance to the source or by changing the angle of illumination.

Benefits

• Experiment is part of a complete solution set with a total of 26 experiments for Renewable Energy solar cells, wind power, water power
• Safe experimentation: the lamp is protected against touch, the housing is well ventilated with the aid of holes and is only slightly heated
• Doubled learning success: Electric circuit diagram on top, real components can be seen at the bottom

Tasks

What influence does the intensity of illumination have on the voltage and current of a solar cell?

Change the intensity of illumination and measure the short-circuit current and the open circuit voltage of the solar cell. Draw a diagram of the measurement values.
