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.
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.
