Transparent metallic conductors are being increasingly utilized in solar cells, display systems and a wide range of opto-electronic devices. Indium-Tin-Oxide (I.T.O.) has been widely employed in this role. Recently, cadmium stannate has also been utilized as an optically transmissive cathode contact in prototype electroluminescent displays (Kirton et. al.). In many instances, the conversion properties of an opto-electronic device are limited by the optical transmission and reflection properties of the interfaces formed between the transparent conductor and other semiconducting materials. These may in turn be controlled by chemical and/or metallurgical reactions occurring at an interface.
