What is the difference?
- 1Source of light: Photoelectric refers to the emission of electrons from a material when light is shone on it, while photovoltaic specifically refers to the conversion of solar energy into electrical energy.
- 2Method of conversion: Photoelectric uses the photoelectric effect to convert light energy into electrical energy, while photovoltaic uses the photovoltaic effect to achieve the same result.
- 3Efficiency: Photovoltaic is generally more efficient at converting solar energy into electrical energy than photoelectric is at converting light energy into electrical energy.
- 4Application: Photoelectric is commonly used in sensors and detectors, while photovoltaic is primarily used in solar panels for generating electricity.
- 5Cost: Photovoltaic systems are typically more expensive to install and maintain than photoelectric systems.
Remember this!
Photoelectric and photovoltaic are both methods of converting light energy into electrical energy. However, the difference between the two lies in their source of light, method of conversion, efficiency, application, and cost. Photoelectric relies on the photoelectric effect and is commonly used in sensors and detectors, while photovoltaic uses the photovoltaic effect and is primarily used in solar panels for generating electricity.
