What are Solar Panels Made of?
Photovoltaic (PV) solar panels are made up of many solar cells. Solar cells are made of silicon, like
semiconductors. They are constructed with a positive layer and a negative layer, which together create an
electric field, just like in a battery.
How Do Solar Panels Generate Electricity?
PV solar panels generate direct current (DC) electricity. With DC electricity, electrons flow in one direction
around a circuit. This example shows a battery powering a light bulb. The electrons move from the negative
side of the battery, through the lamp, and return to the positive side of the battery.
With AC (alternating current) electricity, electrons are pushed and pulled, periodically reversing direction,
much like the cylinder of a car’s engine. Generators create AC electricity when a coil of wire is spun next to
a magnet. Many different energy sources can “turn the handle” of this generator, such as fossil fuel,
hydroelectricity, nuclear, wind, or solar.
AC electricity was chosen for the U.S. electrical power grid, primarily because it is less expensive to
transmit over long distances. However, solar panels create DC electricity. How do we get DC electricity into
the AC grid? We use an inverter.
Solar panels have become much cheaper to use, compared to oil, diesel and liquified natural gas in parts of
Asia. Solar energy will soon become the main source of energy. Over the years many innovations have
been made to improve solar panels. Solar panels have been used for space exploration and are being
developed to be able to power cars. Along with this, scientists are developing solar cells in silicone to
increase its convenience.
