The Shockley–Queisser limit is calculated by examining the amount of electrical energy that is extracted per photon of incoming sunlight. There are several considerations: Any material, that is not at absolute zero (0 kelvins), emits electromagnetic radiation through the black-body radiation effect. In a cell at room temperature, this represents
