(color online) Simulation results of HAC and HIT cells with different wafer thicknesses: (a) variation of conversion efficiency with wafer thickness, (b) variation of short-circuit current density with wafer thickness, (c) variation of open-circuit voltage Voc with wafer thickness, (d) variation of fill factor FF with wafer thickness, (f) quantum efficiency QE as a function of wavelength, and (e) reverse saturation currents J0s with different wafer thicknesses.
