COMPOUND SEMICONDUCTOR SOLAR CELL

WIPO Patent Application WO/2018/216984

A1

There is provided a compound semiconductor solar cell, comprising: a top cell including a compound semiconductor layer; a front electrode located on a front surface of the top cell and including a plurality of finger electrodes; and a back electrode disposed on a back surface of the top cell, wherein the top cell including a first window layer positioned on a light receiving surface of the top cell, a first base layer containing impurities of a first conductive type and located on a back surface of the first window layer, and a first emitter layer containing impurities of a second conductive type opposite the first conductive type and located on a back surface of the first base layer to form a p-n junction with the first base layer, wherein the first base layer includes a first layer having a first electrical conductivity and a second layer having a second electrical conductivity different from the first electrical conductivity, and wherein an interval between the second layer and the first emitter layer is larger than an interval between the first layer and the first emitter layer. The second electrical conductivity of the second layer may be higher than the first electrical conductivity of the first layer.
