  • Publication number: 20230136328
    Abstract: The invention relates to a thin film solar module comprising a monolithic solar cell array (1), including a plurality of solar cells (2) with a layer structure, comprising a rear contact layer (3), a front contact layer (4) and an absorber layer between the rear contact layer and the front contact layer, and an electrical connection structure (6) for electrically serially connecting neighbouring solar cells. The invention also relates to an associated production method. In the thin film solar module according to the invention, the electrical connection structure includes contact strips (7) for electrically serially connecting neighbouring solar cells, wherein the electrical connection structure electrically serially connects two respective solar cells (2m, 2m+1) that are adjacent to one another in a series connection direction (RS) via one or more contact strips (7).

  • Publication number: 20080230736
    Abstract: The invention describes a process for improving the sensory properties of fabrics. The fabrics are treated with a water-based preparation which contains alkyl oligoglycosides in combination with mixtures of mono- and diesters of saturated and unsaturated C16-22 fatty acids with diol and polyols, for example as a spray or in the form of a dryer sheet. The compositions may additionally contain auxiliaries and additives, preferably thickeners, such as in particular polymeric thickeners.

  • Patent number: 7309685
    Abstract: A method for treating fibers, yarns or textiles to improve the sensory effect for a user or weaver of a fabric article. The method treats the fiber, yarns or textiles with an emulsion containing 15-30% by weight of a mixture of waxes having melting points in the range of 35° C. to 60° C. including a lipophilic wax matrix; 10%-20% by weight of emulsifier which are at least one of alkyl or alkenyl oligoglycosides or alkyl ether sulfates, 1%-10% by weight of a crystal regulator which can be partial esters of C12-22 fatty acids with at least one of glycerol, polyglycerol and sorbitan. The mean particle size of the wax crystals is not greater than 6 ?m. The emulsion includes water and auxiliaries and additives.
