A stacked photovoltaic element contains a structure formed by sequentially arranging a metal layer 103, a lower transparent conductive layer 104, a first n-layer 105 of non-single-crystal silicon, a first i-layer 106 of microcrystal silicon, a first player 108 of non-single-crystal silicon, a second n-layer 109 of non-single-crystal silicon, a second i-layer 110 of microcrystal silicon and a second player 112 of non-single-crystal silicon on a support body 102. The first i-layer 106 and the second i-layer 110 are made to contain phosphor and the content ratio R1 of phosphor to silicon of the first i-layer 106 and the content ratio R2 of phosphor to silicon of the second i-layer 110 are defined by the formula of R2 < R1. With this arrangement, photovoltaic elements showing a high conversion efficiency can be manufactured with a high yield factor. <IMAGE>
