A solar cell converts light energy into electrical energy, which can then be consumed normally. The process occurring in a solar cell is called photovoltaic conversion. This is how sunlight is converted into electricity.
Solar cells are not 100% efficient. At this time, the best small solar cells with optimum colour-sensitivity in laboratories have not exceeded 25% efficiency. Commercially available solar cells currently have efficiency rates of between 6% and 16%.
How does a solar cell work?
- Solar cell types
- Watt peak
- Why isn't the efficiency 100%?
