  • Publication number: 20230352607
    Abstract: Translucent photovoltaic product, method of manufacturing the same and manufacturing apparatus. The method comprises: depositing a stack of layers on a carrier substrate, the stack comprising a first electrode layer, a photovoltaic layer and a second electrode layer; cutting through the substrate with the stack of layers to form a first and a second mutually disjoint sections; separating the first and the second section from each other; laminating the first section and the second section with a respective further substrate at a side opposite the carrier substrate to form a respective first and second photovoltaic device; and assembling the photovoltaic product from the first photovoltaic device and the second photovoltaic device, wherein the first and the second sections are mutually complementary comb shaped structures and wherein the second photovoltaic device is arranged in a second plane parallel to and in front of a first plane of said first photovoltaic device.

  • Patent number: 11749766
    Abstract: A photovoltaic device (1) is provided with a first electrode layer (11), a photovoltaic layer (13), a second charge carrier transport layer (14) and a second electrode layer (15). The photovoltaic device (1) has a plurality of mutually subsequent photovoltaic device cells (1A, . . . , 1F) arranged in a first direction (D1). Each pair of a photovoltaic cell (1C) and its successor are serially connected in an interface region (1CD). The interface region comprises an elongate region (R0) between successive first electrode layer portion (11C, 11D), a first elongate region (R1) between successive photovoltaic layer portions (13A, 13B), a second elongate region (R2) between successive second charge carrier transport layer portions (14C, 14D) and a third elongate region (R3) between successive second electrode layer (15) portions (15C, 15D). The second elongate region (R2) extends within the first elongate region (R1), and its lateral boundaries are distinct from those of the first elongate region (R1).

  • Publication number: 20230103676
    Abstract: A semi-translucent photovoltaic device is described having a translucent substrate with a photovoltaic stack interrupted in spatially distributed openings filled with a translucent polymer. Also disclosed is a method of manufacturing the device. The method comprises providing the substrate at a first side with the photovoltaic stack; removing material from the stack in spatially distributed regions, therewith forming openings within these regions; blanket-wise depositing a protective layer over the substrate with the photovoltaic stack; blanket-wise depositing a layer of a radiation-curable precursor for the translucent polymer over the protective layer; irradiating the substrate from a second side opposite its first side to therewith selectively cure the radiation-curable precursor within and in front of the spatially distributed openings, the radiation-curable precursor being converted therewith into said translucent polymer; removing an uncured remainder of the layer of the radiation-curable precursor.

  • Publication number: 20220352402
    Abstract: A photovoltaic device (1) with a plurality of photovoltaic modules (1A, IB, . . . , IF), is disclosed herein comprising a stack with a primary electrode layer (12), a secondary electrode layer (16) and a photovoltaic layer (14) arranged between said primary and said secondary electrode layer, at least one of the electrode layers being translucent, the photovoltaic layer (14) at least comprising a first sublayer of a photovoltaic material and a second, charge carrier transport sublayer between said first sublayer and said secondary electrode layer. An serial electrical interconnection between mutually subsequent photovoltaic modules (IB, 1C) is provided by a coupling element of insulating material laterally enclosing an electrically conducting core (17BC) provided in the interface section between the mutually subsequent photovoltaic modules. Therewith a lifetime of the photovoltaic material is improved.

  • Publication number: 20150086705
    Abstract: A light induced forward transfer manufacturing method provides for transfer of material from a donor sheet. A donor sheet is used that comprises a trench in a surface of the donor sheet, with transfer material in the trench. The material is transferred by scanning a light spot along the bottom of the trench. A donor sheet is used in which the average depth of the trench varies in the scanning direction. This supports optical reading of position information from the trench through the donor sheet and/or transfer of structures with predetermined height profiles from the trench. In combination with the average depth, or by themselves, a trench width, deviation of a trench from an average track or variation of a thickness or composition of material at a bottom of the trench may vary as a function of position along the trench to support optical reading of position information and/or transfer of predetermined structures.
