Abstract
A transparent thin film thermocouple and a method of manufacturing comprig a positive element of indium tin oxide (ITO) and a negative element of indium oxide (In.sub.2 O.sub.3) formed on a surface by reactive sputtering with the elements being electrically joined to form a hot junction for conversion of heat into electricity.
Claims6
A method for producing a transparent thin film thermocouple on a surface comprising the steps of:
- forming a thin film element of indium tin oxide (ITO) with an In:Sn weight fraction ratio of 9:1 on said surface by reactive sputtering;
- and
- forming a thin film element of indium oxide (In.sub.2 O.sub.3) or ITO with a lower tin constant than the positive leg on said surface by reactive sputtering;
- said elements being electrically joined to form a hot junction for conversion of heat into electricity.
