Abstract
In one aspect of the present invention, a method is provided. The method includes disposing a substantially amorphous cadmium tin oxide layer on a support and rapidly thermally annealing the substantially amorphous cadmium tin oxide layer by exposing a first surface of the substantially amorphous cadmium tin oxide layer to an electromagnetic radiation to form a transparent layer. A method of making a photovoltaic device is also provided.
Claims30
A method, comprising:
- disposing a substantially amorphous, electrically resistive cadmium tin oxide layer on a support;
- and
- rapidly thermally annealing the substantially amorphous cadmium tin oxide layer by exposing a first surface of the substantially amorphous cadmium tin oxide layer to an electromagnetic radiation emitted from an incoherent light source to form a transparent layer.
(canceled)
A method, comprising:
- disposing a substantially amorphous, electrically resistive cadmium tin oxide layer on a support;
- and rapidly thermally annealing the substantially amorphous cadmium tin oxide layer by exposing a first surface of the substantially amorphous cadmium tin oxide layer to an electromagnetic radiation emitted from an incoherent light source to form a transparent layer;
- disposing a first semiconductor layer on the transparent layer;
- disposing a second semiconductor layer on the first semiconductor layer;
- and
- disposing a back contact layer on the second semiconductor layer to form a photovoltaic device.
