Correct option is D
A solar cell, also known as a photovoltaic (PV) cell, is a device that converts light energy into electrical energy using the photovoltaic effect. When sunlight strikes the cell, it excites electrons in the semiconductor material (typically silicon), creating a flow of electric current.
About Photovoltaic Effect
- The photovoltaic effect was first observed by the French physicist Edmond Becquerel in 1839.
- The efficiency of converting light into electricity depends on the material used and the design of the solar cell.
- The photovoltaic effect is the process by which a material generates electrical current when it is exposed to light. It is the fundamental principle behind the operation of solar cells or photovoltaic (PV) cells, which convert light energy directly into electrical energy.
