The photosensitive optoelectronic device 1 comprises a plurality of organic semiconductor subcells 10, 11, 12, 13 arranged in a stack between the electrodes, each subcell having a donor material 14 providing heterojunctions. , 16, 23, 25) and acceptor material (15, 17, 24, 26). Recombination layers 19, 22, 28 exist between adjacent subcells. The subcells are arranged in two groups 20 and 29. The subcells 10, 11; 12, 13 in the groups 20; 29 react in the light spectrum of substantially the same area. The groups 20 and 29 are substantially different in the region of the light spectrum with which each subcell reacts. |
