Photovoltaic (PV) Solar Power
When talking about Solar Electricity, we are usually talking about Photolvoltaic (or PV) Solar Power. Photovoltaic Solar Power is solar energy which is converted into electricity using pholtovoltaic solar cells. This is done through the use of specialized machinery.
The ability to capture Photovoltaic energy was first discovered in the mid 1800's, but it was not until 1954 that a team of researchers at Bell Labs found a way to create enough electricity for PV energy to be of any use. This was done (and still is done) through the use of silicon semiconductors. Semiconductors only conduct electricity when exposed to light or heat (as opposed to conductors, which always conduct electricity and insulators which never conduct electricity). The captured light moves along a circuit from Positive-type semiconductors to Negative-type semiconductors in order to create electric voltage.
Home and Business owners can harness PV Power in many ways, including: Solar Electricity, Photovoltaic Cooling, and Photpvoltaic Solar Lighting. Power is collected through a structure compirsed of many solar cells – usually a Solar Power Panel (also called a PV Module). PV Modules/ Solar Panels can be combined into an “array” of panels in order to capture a greater amount of solar energy.
