Abstract: A solar cell is disclosed. The solar cell includes a crystalline semiconductor substrate containing impurities of a first conductivity type, a front doped layer located on a front surface of the semiconductor substrate, a back doped layer located on a back surface of the semiconductor substrate, a front transparent conductive layer located on the front doped layer and having a first thickness, a front collector electrode located on the front transparent conductive layer, a back transparent conductive layer located under the back doped layer and having a second thickness, and a back collector electrode located under the back transparent conductive layer. The first thickness of the front transparent conductive layer and the second thickness of the back transparent conductive layer are different from each other, and a sheet resistance of the front transparent conductive layer is less than a sheet resistance of the back transparent conductive layer.

Abstract: A solar cell is disclosed, which includes a crystalline semiconductor substrate of a first conductive type, a front doped layer on a front surface of the semiconductor substrate and forming a hetero junction with the semiconductor substrate, a back doped layer on a back surface of the semiconductor substrate and forming a hetero junction with the semiconductor substrate, a front transparent conductive layer on the front doped layer, a back transparent conductive layer under the back doped layer. One of the front doped layer and the back doped layer has a second conductive type opposite to the first conductive type to form a p-n junction with the semiconductor substrate, and the other of the front doped layer and the back doped layer has the first conductive type. A planar area of the front transparent conductive layer is larger than a planar area of the back transparent conductive layer.
