A photovoltaic cell ( solar cells) is a term used to describe devices that convert solar radiation directly to electricity. PV’s are a sort of semiconductor that catches the light and turn into pure and clean power. These devices are sound and smoke-free, no moving parts.
Volcanism is a term used to describe the phenomena of volcanic activity. Significant volcanic eruptions spew massive amounts of ash into the atmosphere that absorb solar radiation, thus potentially generating a cooling effect on planetary temperatures.
