METHOD OF PREPARING ELECTRODE OF SOLAR CELL, METHOD OF PREPARING SOLAR CELL, AND SOLAR CELL

摘要

A method for forming an electrode of a solar cell, a method for manufacturing the solar cell, and the solar cell are provided to reduce the reflectance of the solar cell and to increase a thickness of an electrode line by reducing a width of the electrode line. A mold(301) is manufactured according to an electrode pattern. A paste for forming an electrode is injected into the mold and then hardened to form an electrode line(311). The electrode is attached to an adhesive tape(303) where an adhesive is covered. The electrode attached to the adhesive tape is attached to a substrate by using an adhesive agent of which adhesive strength is stronger than that of a gluing agent. The adhesive tape is separated from the electrode line. A heat treatment is performed on the electrode line formed on the substrate. The paste includes silver, a glass frit, and a binder. The adhesive agent is selected from a group consisting of a rubber-based adhesive, an acrylate-based adhesive, and a silicon-based adhesive.
