LIGHT HARVESTING PHOTOVOLTAIC DEVICE |
摘要 |
The invention concerns a photoelectric conversion device comprising: at least one photoconversion element comprising at least one organic photoconversion layer or an inorganic layer comprising quantum dots or perovskites; at least a first grating structure arranged on a first side of the photoconversion element; and at least a second grating structure arranged on a second side of the photoconversion element; wherein said at least a first grating structure is arranged so as to direct a near-infra-red light portion of light incident on said first grating structure into said photoconversion element, the said at least a second grating structure being arranged to reflect at least a part of said near-infra-red light portion back into said photoconversion element and to pass visible light out of the photoelectric conversion device. |

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