Let us have a photo-voltaic circuit. The amount of emf induced in the photo-voltaic material is in direct proportion to the amount of photons(intensity) falling at it. Hence if we move the photo-voltaic material in a direction towards the source of the light, it must generate an increased emf owing to the increased photon intensity due to the relative motion to the photon with respect to the solar cell??? Or is this a violation of theory of relativity???
