Abstract
A method applying a circular photonic crystal structure to improve optical properties of a photoelectric conversion device such as a light emitting diode device, an organic light emitting diode device or a solar cell is provided, wherein the circular photonic crystal structure is configured on a junction surface between two different mediums where passes a light emitted or received by the photoelectric conversion device. The circular photonic crystal structure provides isotropic photonic band gap which conduces high light extraction efficiency.
