13. The set T may more generally include elements (C,C) and (V,V), which represent intraband electronic transitions between distinct states of the conduction and VBs, respectively. If the quasi-Fermi level describing the electronic occupancy in one of these bands approaches or even surpasses the respective band edge, then it is important to include that element in T. The approach here accommodates their inclusion.

36. As explained in Sec., an efficiency calculation that includes the energy flux from the Sun and that exludes the energy flux from the Earth will result in a distorted efficiency that is a factor { 1+ [(1-CD) /CD] (TE / TS) 4 } larger than a calculation using the first-law efficiency that includes both. Allowing that D=2.16× 10-5, C=1, TE =300, and TS =6000, then this factor equates as 1+ (4.63× 104) (6.25× 10-6) =1.29.
