Experiment 1 - The Solar Cell
When light falls on a solar cell, you measure a voltage
at the positive and negative terminals of the cell.
The photovoltaic effect has converted light into an electrical voltage.
Build the circuit as shown...
Circuit diagram voltage of a solar cell.
Circuit voltage of a solar cell.
Once you let light shine onto the solar cell,
your multimeter shows a voltage...
In direct sunlight you measure a voltage close to the nominal voltage,
in artificial light you measure a voltage well below the nominal voltage and
if you cover the solar cell, you measure a voltage close to 0 Volt.
Not only a voltage is generated,
it can also generate a current and performs work...
