Abstract:
1. A method for fabricating a solar tile comprising: providing a flexible circuit comprising at least one electrically conductive path laminated between two insulating sheets; creating a plurality of openings completely through the flexible circuit including the at least one electrically conductive path and the insulating sheets, thereby defining a contact location with the electrically conductive path within each opening; depositing an electrically conductive solder material within each opening such that the electrically conductive solder material and an exposed portion of the electrically conductive path are in electrical communication at the respective contact location; providing a plurality of photovoltaic solar cells having two major opposing surfaces, each solar cell comprising at least one pair of contacts of opposing polarity disposed upon one surface of the solar cell; and securing the plurality of solar cells to the flexible circuit such that the contacts of the solar cells are aligned with the plurality of openings, said securing step comprising reflowing and thereafter cooling the solder material such that the solder material and the contacts of the solar cells are in mechanical and electrical contact.
