Impedance and Interface Properties of Al/Methyl-Red/p-InP Solar Cell
Figure 4
(a) (Color online) /w versus w characteristics obtained from the experimental forward bias capacitance and conductance versus frequency measurements of the Al/methyl-red/p-InP structure in dark. (b) Energy distribution curves of the interface states and their time constants obtained from the experimental /w versus w characteristics for the Al/methyl-red/p-InP structure in dark. (c) The -V characteristic of the Al/methyl-red/p-InP device for 500 kHz frequency in dark (inset represents the -f characteristic of that for 0 volt in dark).
