The saturation currents of minority-and majority-carrier m.i.s. solar cells have been compared to find the value of the barrier height ϕ′ms, where the dominating saturation current changes from a majority-carrier current to a minority-carrier current. For an interfacial oxide layer of 20 Å, the value ofϕ′ms has been calculated to be in the range 750-800 mV, whereas for an oxide layer of 10 Å, ϕ′ms, is found to be about 900-950 mV.
