Organic photosensitive optoelectronic device with near-infrared sensitivity

An organic photosensitive optoelectronic device comprising:

• (i) first electrode and second electrode, wherein at least one of the first electrode and the second electrode is transparent;
• (ii) organic photoactive materials disposed between the first electrode and the second electrode, comprising:
• (a) a first organic semiconductor material;
• and
• (b) a second organic semiconductor material,
• wherein the first organic semiconductor material comprises at least one donor material relative to the second organic semiconductor material with the second organic semiconductor material comprising at least one acceptor material, or the first organic semiconductor material comprises at least one acceptor material relative to the second organic semiconductor material with the second organic semiconductor material comprising at least one donor material, wherein the donor material comprises ClAlPc, and wherein the first organic semiconductor material is in direct contact with the second organic semiconductor material;
• and
• (iii) at least one exciton blocking layer between the two electrodes and adjacent to at least one of the two electrodes.
