Solar cell (or photo voltaic cell) is a device which converts:
Correct answer: B. Light energy into electrical energy
- A. Chemical energy into electrical energy
- B. Light energy into electrical energy
- C. Electrical energy into light energy
- D. Chemical energy into light energy
Explanation
A solar cell, also known as a photovoltaic cell, is a device that converts light energy, typically from sunlight, directly into electrical energy through the photovoltaic effect.When photons (particles of light) strike the semiconductor material within a solar cell, they transfer their energy to the material. This energy excites electrons, allowing them to break free from their atomic bonds, resulting in the creation of electron-hole pairs. The internal electric field within the semiconductor then separates these charge carriers, generating an electric current.In summary, a solar cell or photovoltaic cell converts light energy into electrical energy by utilizing the photovoltaic effect within the semiconductor material.
