The nanotechnological inventions raise competitive ability of the products

A brief description of the nanotechnological inventions is given. The inventions in the area of nanotechnologies and nanomaterials produce a profound effect in construction, housing and communal services and adjacent economic fields as they allow us: to obtain high strength and durability of surfaces of the details, to provide different materials with hydrophil properties, to increase efficiency of transformation of light energy into electrical one etc., and in general - to raise competitive ability of the products. For example, the method of production of solar element and a unit of solar elements (RU 2532137) comprises following stages: formation of pn-transfer in semiconductor base plate, formation of passivating layer on the light-receptive surface and/or non light-receptive surface of semiconductor base plate and formation of power robbing electrodes on the light-receptive surface and non light-receptive. A film of aluminium oxide is formed as passivating layer, its thickness is up to 40 nm, and electrode is formed by baking conductive paste under the temperature 500-900 оC for 1 second - 30 minutes with formation of sintered product. The sintered product penetrates through passivating layer setting electric contact between electrode and base plate. The formation of aluminium oxide with specified thickness on the surface of base plate makes it possible to achieve good passivating characteristics and good electric contact between silica and electrode only by means of baking conductive paste, that is standard technology. Moreover the baking stage which was necessary to get the effect of film passivation for aluminium oxide in the past now can be cancelled to decrease costs.
