Which components can operate when exposed to light

Answer 1

1. Solar panels: Solar panels convert sunlight into electricity by using photovoltaic cells.

2. Photodiodes: Photodiodes are semiconductor devices that can generate an electric current when exposed to light.

3. Phototransistors: Phototransistors can amplify and detect light intensity by converting photons into electrical signals.

4. Light sensors: Light sensors can detect the presence or absence of light and are commonly used in automatic lighting systems.

5. Solar-powered devices: Many devices, such as calculators, outdoor lights, and chargers, can operate using solar energy when exposed to light.

6. OLED displays: Organic Light Emitting Diode (OLED) displays emit light when an electric current is passed through them, making them energy-efficient and suitable for use in low-light conditions.
