  1. a Eg is determined from the EL peak.
  2. b VOC, SQ is the Shockley-Queisser limit of VOC.
  3. c ΔE1  =  Eg  −  qVOC, SQ.
  4. d ΔE2 = q(VOC, SQ  −  VOC, rad), VOC, rad = VOC +  VOC, nr and VOC, nr = − kBT/qln(EQEEL), where VOC is the measured value.
  5. e ΔE3 is the non-radiative recombination, including the losses within subcells (ΔE3subcell) and ICL (ΔE3ICL).
  6. f Eloss = ΔE1 + ΔE2  +  ΔE3  =  Eg  −  qVOC.
