Which of the following is false with reference to a photo-voltaic cell?
- AIt is another name as solar cell
- BIt can be used as infra-red detectors
- CIt can store light energy in the form of electrical energy
- DIt converts electric energy into light energy
Solution & Step-by-step Explanation
Let's evaluate the given statements about photo-voltaic cells:
Option A is True: A photovoltaic cell is commonly known as a solar cell.
Option B is True: Photovoltaic cells can be calibrated and manufactured to detect specific spectrum ranges, including infrared light.
Option C is True: It generates electricity from light, which can then be transferred and stored in devices like batteries in the form of electrical energy.
Option D is False: A photovoltaic cell converts light energy into electrical energy, not vice versa. Devices that convert electrical energy into light energy are Light Emitting Diodes (LEDs) or lamps.
