Question
Certain materials produce electricity when struck by light. They are called as ________.
- Photovoltaic
- Magnetomotive
- Electrolytic
- Chemically active
Hint:
The photovoltaic cells when exposed to sunlight generate the voltage of current.
The correct answer is: Photovoltaic
The material that generates electrical energy when struck by sunlight is photovoltaic.
- The materials that produce electricity on struck by the sunlight are called photovoltaics.
- They convert the thermal energy from the sun into electric energy.
- The photovoltaics when exposed to sunlight generate the voltage of current.
