The invention relates to the production of a photovoltaic structure that includes a thin coating film, generally made of a transparent conductive oxide, deposited on top of a sublayer having photovoltaic properties. According to the invention, the coating film is deposited electrochemically in an electrolysis bath (1) and at least partly assisted by illumination coming from a light source (2).

The invention relates to a method for production of thin layers of semiconductor alloys of the I-III-VI2 type, including sulphur, for photovoltaic applications, whereby a heterostructure is firstly deposited on a substrate comprising a thin layer of precursor I-III-VI2 which is essentially amorphous and a thin layer, including at least some sulphur, the heterostructure is then annealed to promote the diffusion of the sulphur into the precursor layer and the at least partial crystallisation of the I-III-VI2 alloy of the precursor layer with a stoichiometry which hence includes sulphur. A layer of selenium may also be deposited to assist the recrystallisation processes or annealing.

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).
