Study Notes
Solar Cells
- The main function of a solar cell is to convert sunlight into electrical energy.
- Individual solar cell devices are often referred to as photovoltaic (PV) cells.
- A common single-junction silicon solar cell can produce a maximum open-circuit voltage of around 0.6-0.7 volts.
- Photovoltaic cells can serve as a building material, in addition to producing energy, due to their ability to be integrated into building structures.
- The operation of a PV cell requires light, typically in the form of sunlight, to generate electricity.
