We discuss results of surface photovoltage (U) measurements for d=10ćm thick layers of undoped hydrogenated microcrystalline silicon. By applying excitation with low energetic photons a photovolatge peak appears on a curve U=u(ŕ). We present a mathematical model that enable us to link this peak to photocharge separation in the bottom space charge region at the interface ćc-Si:H/substrat.
