THIN-FILM PHOTOVOLTAIC CELL STRUCTURE WITH A MIRROR LAYER

摘要

Thin-layer photovoltaic cell structure with mirror layer. The invention relates to a photovoltaic cell structure intended for solar panel applications. The thin layer photovoltaic cell structure comprises at least one I-III-VI2 alloy layer (CIGS) with photovoltaic properties for the conversion of illuminating light into electricity. In particular, the structure comprises at least: one mirror layer (MR) comprising a surface reflecting (FR) a part of the illuminating light, where said reflecting surface (FR) is facing a first face (F1) of the I-III-VI2 alloy layer for receiving reflected illuminating light on said first face; and one or more first layers (CA, ENC) transparent to the illuminating light for receiving transmitted illuminating light on a second face (F2) of the I-III-VI2 alloy layer opposite to the first face (F1).
