With the famous 2N3055 power transistor it is possible to make a solar cell or photovoltaic cell, a really small one. But with the help of a magnifying glass it produces enough electricity to move a tiny motor. This motor works with a voltage as low as 0.3 Volts. It is very important to use a radiator heat sink. This one is made of aluminum.
