How does solar panels obsorb energy

"How does a solar cell turn sunlight into electricity? In a crystal, the bonds [between silicon atoms] are made of electrons that are shared between all of the atoms of the crystal. The light gets absorbed, and one of the electrons that's in one of the bonds gets excited up to a higher energy level and can move around more freely than when it was bound. That electron can then move around the crystal freely, and we can get a current." http://www.scientificamerican.com/article/how-does-solar-power-work/
There are two types of solar panel, the solar thermal collector, and the photo-voltaic cell. The first simply collects thermal energy from the sun and transfers it to a fluid, usually water. this is useful for domestic hot water, warming swimming pools, and can be used industrially. The photo-voltaic cell responds to visible sunlight and produces a small dc current from semiconductor material such as silicon, doped with impurities. The theory says that photons of light energy cause electrons to be displaced resulting in a current flow.
@Insa , when you copy things word-for-word make sure you cite it.
