The Photoelectric Effect and Its Applications to Solar Cells

Where E is the energy of the electromagnetic radiation, ℏ is the Planck''s constant with a value 1.055*10-34 J.s, ν is the frequency of the electromagnetic radiation, and c is the speed of light (3*10 8 m/s). Thus, light (or electromagnetic radiation) propagates following linear wave equations but can only be emitted or absorbed as discrete elements.
