Abstract
A solar cell is provided that increases a rate of sunlight absorbed into a photoelectric conversion layer by forming a transparent conductive layer into a plurality of layers having different oxygen contents and different light absorption coefficients, and a manufacturing method thereof. The solar cell includes a substrate, a transparent conductive layer, and a photoelectric conversion layer. The transparent conductive layer includes a first layer having a first light absorption coefficient, and a second layer formed on the first layer and having a second light absorption coefficient higher than the first light absorption coefficient.
