A thin-film photovoltaic cell structure with a mirror layer. The invention concerns a photovoltaic cell structure intended for applications in solar panels. The thin-film photovoltaic cell structure comprises at least one layer of I-III-VI2 alloy (CIGS) with photovoltaic properties, for converting an illuminating light into electricity. In particular, the structure comprises at least: - one mirror layer (MR) comprising a reflecting face (FR) for reflecting a portion of the illuminating light, the reflecting face (FR) being opposite a first face (F1) of the layer of I-III-VI2 alloy (CIGS), for receiving, on said first face, a reflected illuminating light, and - one or a plurality of first transparent layers (CA, ENC) transparent to said illuminating light, for receiving an illuminating light transmitted onto a second face (F2) of the layer of I-III-VI2 alloy (CIGS) opposite the first face (F1).

One aspect of the invention relates to a photovoltaic component (10) comprising a set of layers suitable for the production of a photovoltaic device, of which at least a first layer (101) is made from a conductive material in order to form a rear electric contact, a second layer (102) is made from a material that is absorbent in the solar spectrum, and a third layer (106) is made from a transparent conductive material in order to form a front electric contact. The component also comprises an electrically insulating layer (103) disposed between the rear electric contact and the front electric contact, said layer being discontinuous such that the layers of the layer assembly can be stacked in one or more areas (100) in order to form a photovoltaic active zone in each of these areas. The component further comprises a layer (104) of conductive material, which is in electric contact with the aforementioned third layer of transparent conductive material and which is structured to form a peripheral electric contact for each of the photovoltaic micro-cells.
