Which of these statements are correctly matched? 1. Photovoltaic Elec...
Explanation:
Photovoltaic Electricity:
- Photovoltaic cells are devices that convert sunlight directly into electricity.
- These cells are made up of layers of materials that react to sunlight and release electrons.
- These electrons are captured by metal contacts on the cell and routed through an external circuit to generate electricity.
- This process is known as the photovoltaic effect.
Solar-Thermal Electricity:
- Solar thermal electricity is produced by using mirrors or lenses to concentrate sunlight onto a receiver.
- This receiver absorbs the concentrated sunlight and heats up a fluid, which is then used to produce steam.
- The steam drives a turbine, which generates electricity.
Comparison:
- Both photovoltaic and solar-thermal electricity are forms of solar energy.
- However, they use different methods to harness the energy from the sun.
- Photovoltaic cells directly convert sunlight into electricity, while solar-thermal electricity uses mirrors or lenses to concentrate sunlight onto a receiver that heats a fluid to produce steam to generate electricity.
Conclusion:
- Both statements are correctly matched as they describe different methods of generating electricity from solar energy.
