PURPOSE: A solar cell and a manufacturing method thereof are provided to improve a contact force between an emitter and a first electrode by forming the first electrode with a double layer with different air gap forming areas.;CONSTITUTION: A substrate has a first conductive type. A first electrode is extended in a first direction. A second electrode is connected to a substrate. An emitter unit(121) has a second conductive type which is opposite to the first conductive type. A first electrode layer(1411) is connected to the emitter unit. A second electrode layer(1412) is arranged on the first electrode layer.;COPYRIGHT KIPO 2012
