DefinitionA <PHOTOVOLTAIC DEVICE> is a <FunctionalObject> that has the capability of <CREATING> a voltage (or a corresponding electric current) in a material upon exposure to electro-magnetic radiation
Derived from http://en.wikipedia.org/wiki/Photovoltaic_effect|Though the process involved with this device is directly related to the photoelectric effect, the two processes are different and should be distinguished. In the photoelectric effect electrons are ejected from a materials surface upon exposure to radiation of sufficient energy. The photovoltaic effect is different in that the generated electrons are transferred from one material to another resulting in the buildup of a voltage between two electrodes.
