Min, Byungsul Dastgheib-Shirazi, Amir Kurz, Heinrich Wagner, Hannes 2015-01-30T10:52:35Z Kurz, Heinrich Min, Byungsul The measured saturation current density J<sub>0e</sub> of heavily phosphorus-doped emitters of crystalline Si solar cells is analysed by means of sophisticated numerical device modelling. It is concluded that Shockley–Read–Hall (SRH) recombination exceeds Auger recombination significantly; it is caused by inactive phosphorus. This explains the large discrepancies between measured and simulated J<sub>0e</sub> values, observed persist-ently over the last two decades in industrially fabricated Si solar cells. As a consequence, the heavily phosphorus-diffused emitters still bear a significant potential to contribute to higher Si solar cell efficiency levels, if the amount of inactive phosphorus can be reduced.
