Influence of illumination level on voltage and current of a

Principle

The solar cell plays an important role in the development of alternative, non fossil fuels energy sources. It converts light energy directly into electric energy.
The pupils examine whether the distance of the light source affects the generated voltage and current intensity of a solar cell. The essential result of this experiment is that the voltage remains relatively constant, whereas the current intensity strongly decreases when the distance of the light source increases.

In this experiment the lighting changes in accordance to the distance of the solar cell to the light source. The current intensity and voltage of the solar cell will also be measured.

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
  • The power supply used is versatile and is particularly suitable for pupil tests for all ages

Tasks

How does the solar cell behave when the light of the sun decreases?
