Abstract
Various methods for preparing and/or processing electrically conductive aluminum members such as used in electronic circuits and components are described. Also described are various sheet assemblies using patterned aluminum conductive elements as components of electric circuitry. The sheet assemblies can be used as backsheets for back contact photovoltaic cells or as antennas for RFID tags.
Claims21
A method of forming an oxidation resistant aluminum based electrode on an aluminum foil laminate for a photovoltaic back contact c-Si cell, the method comprising:
- providing an aluminum foil laminate including an aluminum foil having a layer of oxidation on the aluminum foil;
- patterning the aluminum foil of the aluminum foil laminate;
- providing an oxygen-free atmosphere along an outer surface of the aluminum foil;
- removing at least a portion of the oxidation from a portion of the aluminum foil to thereby form a region of freshly exposed aluminum;
- and
- depositing at least one layer of an electrically conductive material on the region of freshly exposed aluminum to thereby form the oxidation resistant aluminum based electrode.
