Abstract
A solar cell including a first conductive type semiconductor substrate; a first intrinsic semiconductor layer on a front surface of the semiconductor substrate; a first conductive type first semiconductor layer on at least one surface of the first intrinsic semiconductor layer; a second conductive type second semiconductor layer on a back surface of the semiconductor substrate; a second intrinsic semiconductor layer between the second semiconductor layer and the semiconductor substrate; a first conductive type third semiconductor layer on the back surface of the semiconductor substrate, the third semiconductor layer being spaced apart from the second semiconductor layer; and a third intrinsic semiconductor layer between the third semiconductor layer and the semiconductor substrate.
