<Hans-Joachim Queisser> and <William Shockley> calculated an ideal efficiency limit for a single-junction <solar cell> using <detailed balance>. The cell must emit as well as absorb <photons>, and <radiative recombination> therefore limits the electrical work extracted from illumination even when other losses are removed. Their 1961 analysis varies the <band gap> and allows a specified fraction of non<radiative recombination>. The familiar limit belongs to stated assumptions about the illumination, cell <temperature> and device; it is not one universal numerical efficiency for every photovoltaic design.<Detailed Balance Limit of Efficiency of p-n Junction Solar Cells by William Shockley and Hans-Joachim Queisser>[Journal of Applied Physics 32, 510 (1961), abstract and ideal radiative-recombination model]{ref}
