Solar cells
in solar panels capture energy from sunlight by collecting electrons
accumulated from atoms that emit electrons. In this situation, the sun emits
photons as usual, and the atoms, silicon, absorb the photons. The type
wavelength of the electromagnetic radiation needed for the solar panels can
range from ultraviolet to infrared radiation depending on the type of solar
panels. These atoms emit electrons because the sunlit rays bombard the atoms
with photons and these photons knock the electrons out of the electron clouds
or the shells. The main ingredient in solar cells is silicon. How electricity
is harvested from solar panels are by collecting the electrons emitted from the
atoms and sending them through wires as a current. We receive more or less
electricity from solar panels when there are more sunlight because the more
sunlight that hits the silicon, the more electrons that will be knocked out and
the less sunlight there is, the less photons there will be to knock the
electrons from the atoms. Eventually, the silicon will degrade and will be less
efficient. The number of silicon that are in the excited state decrease as time
goes on.
Hi Ms Lu. I put this on the internet to see if I get in trouble for this
