Abstract
One embodiment of the present invention provides a solar cell. The solar cell includes a photovoltaic structure, a transparent-conductive-oxide (TCO) layer situated above the photovoltaic structure, and a front-side metal grid situated above the TCO layer. The TCO layer is in contact with the front surface of the photovoltaic structure. The metal grid includes at least one of: Cu and Ni.
Claims14
A method for fabricating a solar cell, comprising:
- forming a photovoltaic structure;
- forming a layer of transparent-conductive-oxide (TCO) situated above the photovoltaic structure;
- forming a front-side electrode grid situated above the TCO layer by:
- depositing, using a physical vapor deposition (PVD) technique, one or more metal layers;
- and
- depositing, using an electroplating technique, a copper layer situated above the one or more PVD-deposited metal layers;
- and
- forming a back-side electrode.
