The correct answer is: Solar energy into electric energy
The correct option is b)Solar energy into electric energy.
- Photovoltaic (PV) cells, commonly referred to as solar cells, are non-mechanical devices that convert sunlight directly into electricity.
- Some PV cells can convert artificial light into electricity. PV cells are the basic building blocks of PV systems. Individual cell sizes vary from about 0.5 inches to about 4 inches in diameter. However, the cell can only generate 1 or 2 Watts, which is only enough for small applications such as pocket calculators and wristwatch operation.
