Stacked photovoltaic element and production method thereof

摘要

The stacked photovoltaic element of the present invention is a stacked photovoltaic element comprising a stack formed of a plurality of unit elements each having a pin constitution, and a transparent electrode provided on the surface of a light incident side of the stacked unit elements, wherein the transparent electrode provided on the surface of the light incident side comprises indium tin oxide (ITO), and the transparent electrode has 90% or more and 99.8% or less in transmittivity of a light of the maximum absorption wavelength of a unit element having the smallest current in a light collection efficiency measurement among the plurality of unit elements, and 50 OMEGA / &squ& or more and 300 OMEGA / &squ& or less in sheet resistance. Such a constitution of the present invention provides a stacked photovoltaic element having an excellent photoelectric conversion efficiency and high reliability at a low cost.
