Abstract:
1. A stacked photovoltaic device comprising at least three p-i-n junction constituent devices superposed in layers, each having a p-type layer, an i-type layer and an n-type layer which are formed of non-single crystal semiconductors comprising silicon, wherein the i-type layer of a first p-i-n junction comprises a material selected from the group consisting of a-Si:H, a-Si:F and a-Si:H:F; wherein the i-type layer of a second p-i-n junction comprises a material selected from the group consisting of μc-Si:H, μc-Si:F and μc-Si:H:F; and wherein the i-type layer of a third p-i-n junction comprises a material selected from the group consisting of μc-Si:H, μc-Si:F and μc-Si:H:F and has a thickness of from 1.5 μm to 3.5 μm.
