Photovoltaic Energy

Doctor Robert Fielden heads to the rooftop for renewable energy via photovoltaic power as part of his series of reinventing Las Vegas.

What is photovoltaic energy?
Sunlight is converted to electricity using photovoltaic or solar cells. Photovoltaic (PV) cells are semiconductor devices, usually made of silicon, which contain no liquids, corrosive chemicals or moving parts. They produce electricity as long as light shines on them, they require little maintenance, do not pollute and they operate silently, making photovoltaic energy a clean and safe method of power generation.
