摘要:
The invention relates to the fabrication of a thin-film photovoltaic cell made of silicon or CIGS. A deposition step is provided for at least one metal contact on a stack of thin films that comprises such a cell. In particular, the metal contact is produced from zinc and is produced, in the above-mentioned disposition step, by electrolysis, preferably photo-assisted electrolysis (7).
摘要:
The invention relates to the regeneration of an electrolysis bath for the production of I-III-VIY compounds in thin layers, where y is approaching 2 and VI is an element including selenium, whereby selenium is regenerated in the form Se(IV) and/or with addition of oxygenated water to reoxidise the selenium in the bath to give the form Se(IV).

In one aspect, the invention relates to a photovoltaic component (100) comprising at least one first set of photovoltaic nano-cells (101) each comprising one optical nano-antenna having an electromagnetic resonance in a first resonance spectral band, at least one lateral dimension of the optical nano-antenna being subwavelength in size, and comprising a spectral conversion layer (107) allowing at least part of the solar spectrum to be converted to said first resonance spectral band.
摘要:
A method for preparing an A-B-C2 or A2-(Dx, E1—x)-C4 absorber thin film for photovoltaic cells where 0≦̸x≦̸1, A is an element or mixture of elements selected within Group 11, B is an element or mixture of elements selected within Group 13, C is an element or mixture of elements selected within Group 16, D is an element or mixture of elements selected within Group 12, and E is an element or mixture of elements selected within Group 14. Said method includes: a step of electrochemically depositing oxide from elements selected from among Groups 11, 12, 13, and 14, a step of annealing in a reducing atmosphere, and a step of supplying an element from Group 16.
