PURPOSE:To manufacture the title tandem organic solar battery having high energy conversion efficiency exhibiting stable performances with minimum electrode short-circuiting, etc., by a method wherein the unit cell on a transparent electrode side is composed of a composite layer comprising cadmium sulfide, perylene coloring matter and phthalocyanine coloring matter while the unit cell on an opposite electrode side is composed of a composite layer comprising perylene coloring matter an phthalocyanine coloring matter. CONSTITUTION:The unit cell on a transparent electrode side is composed of a composite layer of successive laminates of a first layer comprising a cadmium sulfide, a second layer comprising perylene coloring matter and a third layer comprising phthalocyanine coloring matter from the transparent electrode side to the opposite electrode side. On the other hand, the unit cell on the opposite electrode side is composed of a composite layer of successive laminates of a first layer comprising a perylene coloring matter film, a second layer comprising a phthalocyanine coloring matter film. Accordingly, when the unit cell is irradiated with light from the transparent electrode side, the light in the photoabsorption region of the perylene coloring matter in the unit cell on the transparent electrode side is hardly attenuated and is used in the unit cell on the opposite electrode side. Resultantly, the title tandem organic solar battery high in energy conversion efficiency and further generating high voltage can be manufactured. |
