N2 - Silicon heterostructures solar cells have very low surface recombination and the resulting cells can achieve high open circuit voltages. We have demonstrated an open circuit voltage for a silicon solar cell at 753 mV. We show high lifetimes on textured substrates with an average of 3 ms using thin layers of doped and intrinsic amorphous silicon and that the lifetimes are consistent across batches. We show that for high measured lifetimes there is a close match between the Implied VOC (measured from photoconductance) and the Actual VOC (as measured on a final cell). Recent measurements with have produced Implied VOC's of 761 mV on textured substrates.
