A method of forming an ohmic contact to a surface of a Cd and Te containing compound film as may be found, for example in a photovoltaic cell. The method comprises forming a Te-rich layer on the surface of the Cd and Te containing compound film; depositing an interface layer on the Te-rich layer; and laying down a contact layer on the interface layer. The interface layer is composed of a metallic form of Zn and Cu.
