Photovoltaic cell are capable of directly converting sunlight into electricity
A simple wafer of silicon
with
wires attached
to the layer.
Current is produced based on types of silicon (n-type and p-type)
used for the layers.
Each cell = 0.5 volts.
Battery needed as
storage.
No moving parts →
do no wear out,
but because they are
exposed
to the weather,
lifespan is about 20 years.
