摘要:
The invention relates to a method for depositing a semiconductor thin layer (CM) comprising at least one sulphide of a metal species, the deposition being performed on a semiconductor film (F) arranged in a chemical bath (BC), the method comprising the steps of: preparing the chemical bath (BC) using at least one sulphurated precursor of said sulphide of a metal species and a salt containing said at least one metal species, the at least one sulphurated precursor containing a thioacid; and forming the thin layer (CM) by illumination by means of a light source (S) of the chemical bath (BC) and the semi-conductive film (F).

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.

The invention relates to a chemical bath for depositing a layer made from at least metal and sulphur. It also relates to a method for depositing such a layer. This bath comprises, in solution: - a metal salt comprising a metal chosen from at least one of the elements from groups IIB and IIIA of the periodic table; and - a sulphur precursor. The bath further comprises a morpholine compound.

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).
