Abstract:
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 an amorphous silicon layer is used as the i-type layer of a first p-i-n junction, a microcrystalline silicon layer is used as the i-type layer of a second p-i-n junction and a microcrystalline silicon layer is used as the i-type layer of a third p-i-n junction; the first to third p-i-n junction layers being in the order from a light-incident side; and wherein an amorphous silicon layer or an amorphous silicon carbide layer is provided between the p-type layer and the i-type layer of the second p-i-n junction.
