Patent ID: 8058093

Claim:
A method of forming an organic photosensitive optoelectronic device comprising: providing a first transparent film comprising a first electrically conductive material, arranged on a transparent substrate; depositing one or more photoconductive organic materials over the first electrically conductive material; depositing a first metal at an initial rate of no more than 1 nm/s over said one or more photoconductive organic materials, wherein said first metal completely covers and is in physical contact with the top and any exposed portions of said one or more photoconductive organic materials and any exposed interfaces with said one or more photoconductive organic materials, to a thickness of no less than 10 nm; and after the thickness of no less than 10 nm is obtained, sputtering a second metal at an increased rate at least three times the initial rate until a cumulative thickness of the first and second metals completely covering the previously exposed portions of said one or more photoconductive organic materials and the previously exposed interfaces with said one or more photoconductive organic materials is at least 250 nm.
