Abstract
Methods for manufacturing a solar cell are provided. The method may include forming a lower electrode on a substrate, forming a light absorption layer on the lower electrode, forming a buffer layer on the light absorption layer, and forming a window layer on the buffer layer. The window layer may include an intrinsic layer and the transparent electrode which have electric characteristics different from each other, respectively. The intrinsic layer and the transparent electrode may be formed by a sputtering process using a single target formed of metal oxide doped with impurities.
