NOVELTY - Stacked photovoltaic mechanism (101) comprises structure made metal layer (103), lower transparent conductive layer (104), two n-layers of non-single-crystal silicon (105, 109), two i-layers of micro crystal silicon, and two p-layers of non-single-crystal silicon on support body. The first and second i-type layers contain phosphor. The ratio of phosphor to silicon of second i-layer is less than the ratio of phosphor to silicon of first i-layer.    USE - For use in solar battery.    ADVANTAGE - The mechanism provides high conversion efficiency and can be manufactured with high yield factor. It does not require expensive raw material gas. It is free from photo-degradation problems. It can produce short circuit current.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for current balance adjustment method for stacked photovoltaic mechanism comprising sequentially arranging first n-layer of non-single-crystal silicon, first i-layers of micro crystal silicon (106), first p-layers of non-single-crystal silicon (109), second n-layer of non-single-crystal silicon, second i-layers of micro crystal silicon (110), and second p-layers of non-single-crystal silicon (112), causing the first and second i-layers to contain spectral sensitivity adjusting atoms, and adjusting the current balance by adjusting the concentration of spectral sensitivity adjusting atoms.
