A red light-emitting diode requires approximately 2 V supply
voltage, that means it cannot be operated with a single solar cell.
The Pupil kit contains a solar battery which supplies the required
voltage. The experiement should make clear how single solar cells
can be combined so that they generate the same voltage as the solar
battery: They have to be switched on in a row, so that their
voltages can be added to each other. The solar battery uses the
same principle.
