The Principles of Photovoltaics: The layers of a solar module. All pv- modules contain a number of layers from the light-facing side to the back: Protection Layer: Usually made from glass, though in thin-film modules this can also be transparent plastic. Front Contact: The electric contact at the front, has to be transparent, as otherwise, light would not get into the cell.
Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
