Abstract: The principle of detailed balance forms the basis of the present thesis. It states that all microscopic processes in thermodynamic equilibrium are equal to their respective counter processes. For solar cells in thermodynamic equilibrium, for example, as many photons get absorbed by the cell as are emitted. Shockley and Queisser used this principle to determine a theoretical conversion efficiency limit for a solar cell with a given band gap energy, using additionally the assumption that all photons with energies higher than the band gap energy are absorbed and that there is zero absorption below the band gap energy. This so-called step-function in absorption is one of the idealizations of the model as no material shows this kind of sharp absorption edge. There are different conventions on how to quantify the band gap energy, each of which is preferentially used in different solar cell technology communities. This band gap energy, for instance, is used to quantify losses that occur in the solar cell with respect to the ideal solar cell after Shockley and Queisser. [...]
