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.
