Photosynthesis. The leaves of plants convert carbon dioxide, water, and nutrient chemicals into plant food via a process called photosynthesis. Without this process, there would be little or no life on the planet.
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.
