Photovoltaics
Solar energy is the energy in the radiation from the Sun. It can be captured by photovoltaic devices to generate electricity directly.
The electromagnetic radiation from the Sun ranges from the shortest waves (which are gamma rays) to the longest waves (which are radio waves).
Visible light has a wavelength from 400 to 770 nanometres, and it behaves as both a wave and a particle. Electromagnetic radiation in this range is known as a photon.
When photions strike a photovoltaic cell they generate electricity.
