SOLAR CELL USING PHOTOVOLTAIC EFFECT AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A solar cell and a manufacturing method thereof are provided to improve photoelectric conversion efficiency by reducing the contact resistance of a connection line and a back contact electrode.;CONSTITUTION: A first through groove separates a back surface electrode layer(200) from back contact electrodes. The back surface electrode layer is formed on a support substrate. A first contact pattern is formed in the first through groove. A light absorption layer(300) includes a second contact pattern formed on the first contact pattern. A front electrode layer(600) is formed on the light absorption layer.;COPYRIGHT KIPO 2013
