Patent ID: 8441001

Claim:
A photodetector comprising: a structured first electrode comprising a plurality of sub-electrodes that are all separated from each other by spaces therebetween; a second electrode; at least one first organic layer and a second organic layer disposed between said first and second electrodes, one of said first and second organic layers comprising photoactive material that interacts with light to generate electrical charges; said at least one first organic layer and said second organic layer each being structured in conformity with said first electrode to subdivide said at least one first organic and said second organic layer into a plurality of active regions stacked directly above and respectively associated with the sub-electrodes of said first electrode, with the plurality of active regions in said at least one first organic layer all being separated from each other by spaces in said at least one first organic layer that are directly above said spaces between said sub-electrodes, and the plurality of active regions in said second organic layer also all being separated from each other by spaces in said second organic layer that are directly above said spaces between said sub-electrodes; and additional material that completely fills said spaces between said active regions that separate said active regions from each other and that is in place in said active regions while said photoactive material generates said charges.
