THIN-FILM PHOTOVOLTAIC CELL STRUCTURE WITH A MIRROR LAYER

摘要

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).
