Abstract:
1. A method of manufacturing a solar cell, comprising: forming a transparent conductive layer on a substrate by depositing a transparent conductive oxide under room temperature; crystallizing the transparent conductive layer by irradiating a laser beam to the transparent conductive layer using a first laser; selectively etching the crystallized transparent conductive layer to form embossed and depressed patterns at a surface of the transparent conductive layer; forming transparent electrodes in unit cells by patterning the transparent conductive layer having the embossed and depressed patterns; forming a p-n junction semiconductor layer on the transparent electrodes and patterning the p-n junction semiconductor layer; and forming rear electrodes on the patterned p-n junction semiconductor layer by forming a metallic material layer and patterning the metallic material layer, the rear electrodes corresponding to the unit cells.
