    摘要: The invention concerns a photoelectric conversion device (1) comprising:
    at least one photoconversion element (10) comprising at least one organic photoconversion layer;
    at least a first grating structure (20) arranged on a first side of the photoconversion element;
    at least a second grating structure (30) arranged on a second side of the photoconversion element;
    wherein said at least a first grating structure (20) is arranged so as to direct a near-infra-red light portion of light incident on said first grating structure (20) into said photoconversion element (10), the said at least a second grating structure (30) being arranged to reflect at least a part of said near-infra-red light portion back into said photoconversion element (1) and to pass visible light out of the photoelectric conversion device.
