Applications of Photoelectric Effect (pg 244-245)
1. LED lamps along road 💡
- in daylight, photoelectric effects of solar cells enables electrical energy to be stored in battery
- at night, LED lamps will light up with power from battery 🔋.
2. Solar power cells
3. light detectors in automatic doors
- use infrared beam & photocells
- when light path is disturbed, photoelectric current in photocell circuit will be disconnected
- door remain open
4. image sensor 📸
- use to convert light into electrical signals
- electrical signals can be processed to form digital images
5. operation of ISS 🛰️
- depends on source of electrical energy generated from solar panels
- has 16 wings of solar panels that capable to generate 84-120kW of electricity.
