Abstract
Abstract An electrode structure of a solar cell includes a metal wire fixed to the light incident surface of the solar cell with an electrically conductive adhesive. An electrode production method of a solar cell includes applying an electrically conductive adhesive to at least one of a portion of a metal wire and a portion of the light incident surface of the solar cell, pressing the metal wire into a predetermined position of the light incident surface of the solar cell, and solidifying the conductive adhesive to fix the metal wire.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
101 words
A method of making a solar cell electrode comprising: applying an uncured electrically conductive adhesive to a portion of a metal wire by contacting the metal wire with a predetermined thickness of the adhesive spread on a substrate; pressing the metal wire toward the light incident surface of the solar cell with the uncured electrically conductive adhesive between and contacting the metal wire and the light incident surface of the solar cell; and while pressing the metal wire toward the light incident surface, curing the conductive adhesive, thereby bonding the metal wire to the light incident surface of the solar cell.
Claim 2
Independent Claim
101 words
A method of making a solar cell electrode comprising: applying an uncured electrically conductive adhesive to a portion of a metal wire by contacting the metal wire with a predetermined thickness of the adhesive spread on a substrate; pressing the metal wire toward the light incident surface of the solar cell with the uncured electrically conductive adhesive between and contacting the metal wire and the light incident surface of the solar cell; and while pressing the metal wire toward the light incident surface, curing the conductive adhesive, thereby bonding the metal wire to the light incident surface of the solar cell.
Claim 3
Dependent Claim
33 words
The method of claim 10 including heating the conductive adhesive to cure the adhesive while pressing the metal wire toward the light incident surface of the solar cell with the conductive adhesive therebetween.
Claim 4
Dependent Claim
18 words
The method of claim 2 including heating the conductive adhesive by passing a current through the metal wire.
Claim 5
Independent Claim
133 words
A method of making a solar cell including: applying an uncured electrically conductive adhesive to at least a portion of a light incident surface of a solar cell and curing the electrically conductive adhesive on the light incident surface; applying an uncured electrically conductive adhesive to a portion of a metal wire by contacting the metal wire with a predetermined thickness of the adhesive spread on a substrate; pressing the metal wire and uncured electrically conductive adhesive on the wire against the cured electrically conductive adhesive on the light incident surface of the solar cell; and while pressing the metal wire toward the light incident surface, curing the uncured electrically conductive adhesive, thereby bonding the metal wire to the previously cured electrically conductive adhesive on the light incident surface of the solar cell.
Claim 6
Independent Claim
133 words
A method of making a solar cell including: applying an uncured electrically conductive adhesive to at least a portion of a light incident surface of a solar cell and curing the electrically conductive adhesive on the light incident surface; applying an uncured electrically conductive adhesive to a portion of a metal wire by contacting the metal wire with a predetermined thickness of the adhesive spread on a substrate; pressing the metal wire and uncured electrically conductive adhesive on the wire against the cured electrically conductive adhesive on the light incident surface of the solar cell; and while pressing the metal wire toward the light incident surface, curing the uncured electrically conductive adhesive, thereby bonding the metal wire to the previously cured electrically conductive adhesive on the light incident surface of the solar cell.
