Patent ID: 7973308

Claim:
An organic-semiconductor-based infrared receiving device for receiving energy in a predetermined wavelength range of infrared light from a light source, comprising: an electrode layer having a positive layer and a negative layer to form an electric field; and a transport layer being located between the positive layer and the negative layer, and having a first predetermined semiconductor material and a second predetermined semiconductor material combined in a predetermined ratio; wherein the first and the second predetermined semiconductor material themselves do not absorb infrared wavelength, and the energy in the predetermined infrared wavelength range is received at an interface between the first and the second predetermined semiconductor material to form electron-hole pairs, which are then parted into a plurality of electrons and holes; and wherein the plurality of negative electrons and the plurality of holes are driven by the electric field to move to the negative layer and the positive layer, respectively, so that a predetermined amount of photocurrent is generated.
