STRUCTURE FOR IMPROVING ADHESIVE STRENGTH IN SOLAR CELL WITH PLATED ELECTRODE AND METHOD THEREOF

摘要

Disclosed are a structure for improving adhesive strength in a solar cell and a method thereof. If a plating electrode is used as the front electrode of a solar cell where a finger line electrode are separated from a bus bar electrode to reduce the amount of expensive Ag used, an adhesive force is reduced so that a problem can be caused in a post ribbon soldering process. Therefore, a sealing part holding both ends of a bus bar electrode, the front electrode is formed by coating the edge of a substrate with a resist material. Thereby, manufacturing cost reduction and high efficiency are realized by reducing the amount of expensive Ag used in forming the front electrode. And also, the adhesive strength property of the silicon interface of a substrate can be improved.
