"WebThe present chapter uses the principle of detailed balance to derive the classical Shockley and Queisser (SQ)-theory. A generalization of the SQ-theory is developed, which contains the classical SQ-case as a limiting situation and makes predictions about the opto-electronic properties of real world solar cells in terms of an opto-electronic reciprocity relation.
