Study Notes
Photovoltaic Cells
- Photovoltaic cells are devices that convert sunlight directly into electricity through the photovoltaic effect.
- This process involves the absorption of light energy by a semiconductor material, leading to the generation of electron-hole pairs.
- These cells produce direct current (DC) electricity.
- Inverters are used to convert DC electricity to alternating current (AC) for household and industrial applications.
