Cr-MIS solar cells having a 2-cm2 area have been fabricated to produce 12.2% efficiency on single crystal and 8.8% efficiency on polycrystalline Si. Surface-state data were used to predict open-circuit voltages of 0.60 and 0.50 V, respectively, for the single-crystal and polycrystalline Si. Spectral response measurements and Cr metal thickness confirm the differences in short-circuit current density using these two types of Si.
