Using Diode As a Solar Cell

Here presented is my experiment on working of diode as a solar cell. If we keep diode in sunlight or in the source of light, it will generate volts.

Read the instructable to know how to do this thing.

Diodes are like valves of water. The allow to flow the current in only one direction and that is from positive to negative.

This is because they have a depletion layer made when the current tries to flow from negative to positive.

But, How they can Generate Electricity?

Connect the positive terminal of the diode to the negative terminal of Multi meter.

And connect the negative terminal of diode to positive terminal of Multi meter.

Now, keep the Diode in full light and you will see that in multi meter shows the voltage.

Here are some markings in the multi meter.

For getting maximum voltage, you should keep them in series.

For getting maximum current you should keep them parallel connection.
