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.
