Abstract:
A photovoltaic device having a substrate, a layer of Cd2SnO4 disposed on said substrate as a front contact, a thin film comprising two or more layers of semiconductor materials disposed on said layer of Cd2SnO4, and an electrically conductive film disposed on said thin film of semiconductor materials to form a rear electrical contact to said thin film. The device is formed by RF sputter coating a Cd2SnO4 layer onto a substrate, depositing a thin film of semiconductor materials onto the layer of Cd2SnO4, and depositing an electrically conductive film onto the thin film of semiconductor materials.
Abstract:
A method for producing transparent p-type conducting oxide films without co-doping plasma enhancement or high temperature comprising: a) introducing a dialkyl metal at ambient temperature and a saturated pressure in a carrier gas into a low pressure deposition chamber; and b) introducing NO alone or with an oxidizer into the chamber under an environment sufficient to produce a metal-rich condition to enable NO decomposition and atomic nitrogen incorporation into the formed transparent metal conducting oxide.
