The photovoltaic effect in a solar cell can be illustrated with an analogy to a child at a slide. Initially, both the electron and the child are in their respective "ground states." Next, the electron is lifted up to its excited state by consuming energy received from the incoming light, just as the child is lifted up to an "excited state" at the top of the slide by consuming chemical
