Photovoltaics: A Question And Answer Primer
Of all the solar energy technologies, photovoltaics (PV) show the greatest promise for worldwide acceptance and application. Their universal appeal lies in the fact that they generate electricity from the sun. Working photovoltaics have no moving parts, are relatively simple in design, need very little maintenance and are environmentally benign. They simply and silently produce electricity whenever they are exposed to light.
