illustrates that some losses limit the voltage of the cell while others limit its current. This is why angle mismatch, Carnot and emission losses are distinguished even though they stem from the same physical mechanism: radiative recombination. In fact, any recombination process has this dual impact: (1) a current loss because some excited charges don’t make it to the external circuit and (2) a voltage loss because the generation–recombination balance is diminished thus reducing the voltage that can build in the cell.
