=====Solar Basics=====
 
A solar cell is created to do one paramount task.  That is the production of [[electricity]] through the absorption of photons.  When light, in this case radiant energy from the sun, strikes the cell, a certain portion of it is absorbed within the semiconductor material. The semiconductor material in this case is that of the gallium arsenide.  This means that the energy of the absorbed light is transferred to the semiconductor, in our case the gallium arsenide.  The energy excites electrons, knocking them loose or otherwise removing them from their previous bound state.  This allows them to flow freely.  Solar and photo voltaic cells also have one or more electric fields that act as a mediator.  This field forces electrons liberated by light absorption to flow in a certain direction.  This flow of electrons, like many others, is a current.  This current can be harnesssed by placing metal contacts on the top and bottom of the cell.  With these newly placed contacts the current can be drawn off to power just about any external application.
