Abstract: The present invention provides a method for covering a substrate, and includes the following operations: (a) admixing at least four different silane monomers and at least one bi-silane to a first solvent(s) to form a mixture, with the proviso that at least one of the silane monomers or the bi-silane comprises an active group capable of achieving cross-linking to adjacent siloxane polymer chains of the siloxane polymer composition; (b) subjecting the mixture to an acid treatment so that the silane monomers are at least partially hydrolysed, and the hydrolysed silane monomers, the silane monomers and the bi-silane are at least partially polymerized and cross-linked; (c) optionally changing the first solvent to a second solvent; and (d) subjecting the mixture to further cross-linking of the siloxane polymer to achieve a predetermined degree of cross-linking, depositing the siloxane polymer composition on the substrate, and optionally curing the deposited siloxane polymer composition.

Abstract: A method of passivating a silicon substrate for use in a photovoltaic device, comprising providing a silicon substrate having a bulk and exhibiting a front surface and a rear surface, and forming by liquid phase application a dielectric layer on at least said rear surface. The dielectric layer formed at the rear surface is capable of acting as a reflector to enhance reflection of light into the bulk of the silicon substrate, and the dielectric layer is capable of releasing hydrogen into the bulk as well as onto a surface of the silicon substrate in order to provide hydrogenation and passivation. The present invention provides an inexpensive, low cost method of improving the electrical and/or optical performance of photovoltaic devices through the application of coating chemicals onto the backside of the silicon substrate.

Abstract: A method of producing a photovoltaic cell having a cover, comprising the steps of: providing a photovoltaic cell which comprises a crystalline silicon substrate; providing a transparent substrate; forming an antireflective coating on said transparent substrate to provide a coated transparent substrate; and covering the photovoltaic cell with said coated transparent substrate. The antireflective coating is a hybrid organic-inorganic material having an inorganic portion comprising silicon, oxygen and carbon, and further comprising an organic portion with organic groups connected to the inorganic portion. Methods of producing solar panels, coated glass substrates as well as antireflection coatings are disclosed as well as novel compositions of hybrid organic-inorganic materials.

Abstract: A layered structure comprising a substrate layer; and a layer of a siloxane polymer on the substrate layer, the layered structure being capable of being bent about a mandrel having a radius of curvature without breaking. The layer of the siloxane polymer has a thickness of 1 to 50 μm, in particular about 5 to 20 μm, and it is obtained by depositing on the substrate a composition comprising at least three different silane monomers, including at least one bi-silane; at least one of the silane monomers having an active group capable of achieving cross-linking to adjacent siloxane polymer; at least partially hydrolyzing the silane monomers to form siloxane polymer chains; and cross-linking the siloxane polymer chains so as to achieve a cross-linked siloxane polymer layer on the substrate.
