Sunlight consists essentially of small packets of energy called photons. Photons contain different amounts of energy depending on the wavelength of the solar spectrum. For example, blue light or ultraviolet light has more energy than red or infrared light.
When photons strike a photovoltaic cell, some are reflected, some pass through it, and others are absorbed by the photovoltaic cell. These last photons are the ones that produce electric current. These photons cause the electrons in the photovoltaic cell to move to another position and, as we know, electricity is nothing more than the movement of electrons.
This simple principle of physics is the basis for one of the most advanced electricity-generation technologies of our time.
