Patent ID: 8088512

Claim:
A method of preparing an electronic device comprising: combining a plurality of first particles, a plurality of second particles and a crosslinkable polymer precursor to a solid polymer electrolyte, said first and second particles selected to exert a repelling force on each other when combined with said crosslinkable polymer precursor; wherein the first particles have a refractive index n 1 , the second particles have a refractive index n 3 , the polymer precursor has a refractive index n 2 , and n 1 <n 2 <n 3 ; segregating at least a portion of the first particles into a first spatial region that is essentially free of the second particles to form a network of electrically connected first particles to form a first electrode; segregating at least a portion of the second particles into a second spatial region that is essentially free of the first particles to form a network of electrically connected second particles to form a second electrode, wherein the polymer precursor is in communication with both the first and second electrodes; and crosslinking the polymer precursor to form a solid polymer.
