Contact formation of silicon solar cells using conductive ink with nano-sized glass frit

摘要

PURPOSE: A contact formation of silicon solar cells using conductive ink with nano-sized glass frit is provided to minimize the loss of electrode material and to reduce production costs. CONSTITUTION: An emitter layer(202) is formed on the upper part of a substrate. A reflection barrier layer is formed on the emitter layer. A first conductive layer(204) is patterned in the reflection barrier layer. A second conductive layer(205) is formed in the upper surface of the first conductive layer. A conductive ink composite is used in the process for forming the second conductive layer.
