Abstract
An organic polymer photo device with broadband response and high photo-responsitivity includes an anode terminal with a hole transporting network, and a cathode terminal with an electron transporting network. Positioned in electrical communication with the hole transporting network and the electron transporting network is a blended material that has at least one organic polymer light absorbing component. The organic light absorbing component is configured to have a collection length that is larger than the distance to the nearest electron transporting network and hole transporting network. As such, the blended material forms a light absorbing area that has a dimension that is greater than the collection length of the organic polymer light absorbing component.
