Abstract of the Disclosure

A semiconductor device includes a passivating layer to reduce and stabilize the surface recombination rate. The passivating layer is of polycrystalline semiconductor material and is of the same conductivity type as that of the underlying semiconductor material. The semiconductor material of the passivating layer differs from that of the underlying semiconductor layer and has a larger energy gap than the underlying layer
