100〜500人が好ましい。The thickness of the first layer made of cadmium sulfide is not particularly limited, but as it becomes thinner, pinholes are more likely to occur. As the conversion efficiency decreases,
Preferably 100 to 500 people.

が好ましい。The second layer can generate a sufficient electromotive force even if it is a very thin film, and the same effect can be achieved even if the film has pinholes or is discontinuous. Demonstrate. The thickness of the film is not particularly limited, but if it becomes thin, sufficient electromotive force cannot be generated, and if it becomes thick, the light absorption wavelength range of perylene dyes (450 to 6
00 nm) becomes too large, and when light passes through the unit cell on the transparent electrode side, the light attenuates and the electromotive force in the unit cell on the counter electrode side decreases, so 10 to 100 people is preferable. .

Unit cells are provided, and among the unit cells, the unit cell on the transparent electrode side has a first layer made of a cadmium sulfide film and a second layer made of a perylene dye thin film from the transparent electrode side to the counter electrode side. It is a composite layer in which a third layer consisting of a perylene dye film and a third layer consisting of a phthalocyanine dye film are sequentially laminated, and the unit cell on the counter electrode side is a layer X consisting of a perylene dye film and a second layer consisting of a phthalocyanine dye film. Because it is a composite layer with layers stacked one after another,
When light is irradiated from the transparent electrode side, the light absorption region of the perylene dye (450 to 60
0 nm), and the light in that wavelength range can be used in the unit cell on the opposite electrode side. As a result, the tandem organic solar cell has excellent energy conversion efficiency.
However, high voltage can be obtained. Additionally, the stacking of unit cells makes pinholes less likely to occur, resulting in a tandem organic solar cell with stable performance and no short circuit between electrodes.
なお、上記タンデム型有機太陽電池は、液晶表示素子等
の駆動用電池として好適に使用される。The tandem organic solar cell described above is suitably used as a battery for driving liquid crystal display elements and the like.
