Abstract
Thin films of cuprous oxide on thin copper foil, when heat treated in an inert atmosphere and quenched, not only exhibit a 10- to 100-fold increase in photovoltaic effects, but also provide ohmic copper-cuprous oxide contacts when selected portions of the oxide film are first subjected to reducing conditions.
