Solar panels are pretty expensive, but
they are good to save money on
electricity.
They take something from the sun and
do something with it to make it
power stuff.

N-type semiconductor
A semiconductor type in which the density of holes in the
valence band is exceeded by the density of electrons in
the conduction band. N-type behaviour is induced by the
addition of donor impurities, such as arsenic or
phosphorus, to the crystal structure of silicon. In N-type
semiconductors, electrons are the majority carriers, and
holes are the minority carriers.
P-type semiconductor
A semiconductor type in which the density of electrons in the
conduction band is exceeded by the density of holes in the
valence band. P-type behaviour is induced by the addition of
acceptor impurities, such as boron, to the crystal structure of
silicon. In P-type semiconductors, holes are the majority
carriers, and electrons are the minority carriers.
Solar panels are big square disks that take
light energy from the sun and convert it to
a different type of energy called electricity.
A solar cell (also called photovoltaic cell
or photoelectric cell)is made of
monocrystalline silicon wafers
