The transition from light into electricity is made according to the photoelectric effect:When a proton touches on a piece of silicon, one of two things will happen:1. The Photon transmission through a piece of Silicon. This usually occurs when the energy of the lower energy photons sufficient to put electrons to higher energy levels up.2. The energy of a photon is absorbed by the Silicon. This usually occurs when the energy of the photon is greater than the energy to give up electrons to higher energy levels
