Abstract: A method for optimizing an existing generator system based on photovoltaic cells and provided with an existing photovoltaic panel or a group of existing photovoltaic panels, each panel having a first plurality of cells of a first type interconnected in series or in series/in parallel. The method includes: determining an operating voltage of the panel(s); producing additional panel module(s) having a second plurality of thin-film cells of a second type and having a different band gap width than the cells of the panel(s), the additional module(s) being configured to supply an operating voltage equal, within ±10%, to the voltage of the panel(s); positioning the additional module to overlap on or under the panel or one of the panel(s), the module being connected in parallel to the panel(s), or positioning several additional modules to overlap on or under several panels, the several modules being connected in parallel to panels.

Abstract: The invention relates to a process for the preparation of a semiconductor material comprising at least one entirely monocrystalline semiconductor layer, said process comprising the steps of preparation of the surface of a first substrate to receive a monocrystalline silicon layer; deposition by Plasma-Enhanced Chemical Vapor Deposition (PECVD) of a layer of monocrystalline silicon by epitaxial growth with a growth rate gradient on the silicon layer monocrystalline obtained in step (i); and epitaxial growth of a monocrystalline layer of a semiconductor material on the monocrystalline silicon layer obtained in step (ii), to thus obtain a material comprising at least one entirely monocrystalline semiconductor layer. The invention also relates to a multilayer material comprising a monocrystalline layer of semiconductor material.
