  • Publication number: 20220167897
    Abstract: A method of manufacturing a skin-compatible electrode (100) comprises printing a circuit pattern (P1) onto a flexible substrate (200) to form an electrically conductive pattern including an electrode pad area (301). A layer of an adhesive composition (401p) is printed in a second pattern (P2) onto the electrode pad area (301) to form an adhesive interface layer (401). The adhesive interface layer (401) is a dry film formed from the adhesive composition (401p) comprising an ionically conductive pressure sensitive adhesive composition comprising a resin (R), an ionic liquid (I), and optionally electrically conductive particles (P). A layer thickness and material of the flexible substrate, the conductive pattern, and the conductive adhesive interface have relatively low stiffness in plane of the flexible substrate (200).

  • Patent number: 8802485
    Abstract: In the frame of manufacturing a photovoltaic cell a layer (3) of silicon compound is deposited on a structure (1). The yet uncovered surface (3a) is treated in a predetermined oxygen (O2) containing atmosphere which additionally contains a dopant (D). Thereby, the silicon compound layer is oxidized and doped in a thin surface area (5).

  • Patent number: 7981776
    Abstract: The inventive method for depositing silicon onto a substrate firstly involves the introduction of a reactive silicon-containing gas and hydrogen into the plasma chamber and then the initiation of the plasma. After initiating the plasma, only reactive silicon-containing gas or a gas mixture containing hydrogen is supplied to the plasma chamber in an alternatively continuous manner, and the gas mixture located inside the chamber is, at least in part, simultaneously withdrawn from the chamber. From the start, homogeneous microcrystalline silicon is deposited onto the substrate in the presence of hydrogen.

  • Publication number: 20110129954
    Abstract: In the frame of photovoltaic cell manufacturing a silicon compound layer is deposited upon a carrier structure. Manufacturing flexibility is increased on one hand by incorporating ambient air exposure of such silicon compound layer and on the other preventing deterioration of reproducibility by such ambient air exposure by enriching the surface of the addressed silicon compound layer which is to be exposed to ambient air to an oxygen enrichment.
