ABSTRACT:
An amorphous solar cell is provided having a junction structure of a p layer, an i layer and n layer where an electromotive force is generated when the cell is irradiated by light. The amorphous solar cell includes an upper cell and a lower cell which each have an i layer. The upper and lower cells are stacked so that the upper cell is located on the light incident side. An output end of the upper cell and an output end of the lower cell are connected in parallel. The thickness of the i layer of the lower cell is 3000 .ANG. or less. Because the thickness of the i layer of the lower cell is 3000 .ANG. or less, the amorphous solar cell has a high initial photoelectric conversion efficiency and properties which are unlikely to be degraded by light.
