Instabilities have been observed in the electric and photovoltaic characteristics of InP (MIS) Schottky barrier solar cells. The degradation has been more serious for n-type sample than for p-type sample. The degradation in n-type sample seems to be caused by the decrease of the barrier height and in p-type sample, it seems to be explained in terms of the increase in sheet resistance of the gate metal.
