Patent ID: 8623684

Claim:
A method for forming an organic optoelectronic device, comprising: providing a first electrode; coating a first solution on the first electrode, wherein the first solution is a solution or suspension comprising a plurality of micro/nano inorganic semiconductor structures and a first solvent, and after the first solvent is removed, the micro/nano inorganic semiconductor structures are stacked to form a first inorganic semiconductor layer on the first electrode in a physical manner; forming an organic semiconductor layer on the first inorganic semiconductor layer; coating a second solution on the organic semiconductor layer, where the second solution is a solution or suspension comprising a plurality of micro/nano inorganic semiconductor structures and a second solvent, and after the second solvent is removed, the micro/nano inorganic semiconductor structures are stacked to form a second inorganic semiconductor layer on the organic semiconductor layer in a physical manner; and forming a second electrode on the second inorganic semiconductor layer; wherein an annealing step is not needed during and after forming the first inorganic semiconductor layer and the second inorganic semiconductor layer.
