Principle

The pupils should examine a parallel connection of solar cells by measuring the open circuit voltage, Uges, and the short-circuit current, Iges

Using a connection in parallel, greater currents can be reached.

Furthermore, the currents I1 and I2 at each solar cell will be measured. Using this information and Iges, the relation relation for the parallel connection of the solar cells can be derived: Iges = I1 + I2.

The voltage at each solar cell is equal to the open circuit voltage, Uges: Uges = U1 = U2.
