An organic polymer photo device with broadband response and increased photo-responsitivity

A photo device comprising:

• an anode terminal including a hole transporting network and a cathode terminal including an electron transporting network;
• and
• a blended material including a plurality of light absorbing components, each said light absorbing component positioned in electrical communication with said hole transporting network and said electron transporting network;
• wherein each one of said plurality of organic light absorbing components has a collection length that is larger than a distance to the nearest electron transporting network and hole transporting network, and wherein each said one organic light absorbing component configured to absorb light in a different frequency band, and said blended material having a light absorbing area with a dimension that is greater than the collection length of any of said plurality of organic light absorbing components.

A method of fabricating a photo device comprising:

• providing an anode terminal having a hole transporting network and a cathode terminal including an electron transporting network;
• adjusting at least one organic light absorbing component to have a collection length that is larger than a distance to the nearest electron transporting network and hole transporting network;
• and
• forming a blended material that includes said organic light absorbing component, particles of said hole transporting network and particles of said electron transporting network, said blended material in electrical communication with said hole transporting network and said electron transporting network;
• wherein said blended material defines a light absorbing area that has a dimension that is greater than said collection length of said organic light absorbing component.
