Whether on a solar-powered calculator or an international space
station, solar panels generate electricity using the same principles of
electronics as chemical batteries or standard electrical outlets. With solar
panels, it's all about the free flow of electrons through a circuit.
To understand how solar panels generate electrical power, it might help to
take a quick trip back to high school chemistry class. The basic element of
solar panels is the same element that helped create the computer revolution --
pure silicon. When silicon is stripped of all impurities, it makes a ideal
neutral platform for the transmission of electrons. Silicon also has some
atomic-level properties which make it even more attractive for the creation of
solar panels.
