Abstract:
1. A method of fabricating a solar cell, comprising: depositing zinc oxide on a transparent substrate within a temperature range of about 150 ° C.˜180 ° C. to form a first transparent conductive layer on the transparent substrate; texturing an upper surface of the first transparent conductive layer using an etchant solution containing an acetic acid, wherein the amount of the acetic acid in the etchant solution is about 1 wt % to 4 wt %; forming a photoelectric conversion layer on the first transparent conductive layer; forming a second transparent conductive layer on the photoelectric conversion layer; and forming a rear electrode on the second transparent conductive layer, wherein the first transparent conductive layer has defects and non-uniform crystallization.
