The [[wikipedia:Sun|sun]] is the star at the center of the solar system, it has been shinning for more than 4-billion years. It is a nearly perfect sphere of hot plasma with internal convective motion that generates a magnetic field via a [[wikipedia:Solar_dynamo|dynamo]] process.

Some stars are enormous sources of X-rays; others mostly generate radio signals. The sun, while producing these and other energies, releases 95% of its output energy as light, some of which cannot be seen by the human eye.

Now what? The electrons and holes are free and excited with nowhere to go. The continual incident rays of the photons continue to generate electron hole pairs and charge separation causes the presence of uncombined excess negative charges on the n-type side and excess holes on the p-type side, a charge imbalance exists in the cell.

If we then connect the n-type side to the p-type side of the cell by means of an external electric circuit, current flows through the circuit (which responds just as if powered by a battery} because this reduces the light induced charge imbalance in the cell.
