Abstract: A roofing membrane may include a main body, a first material, and a second material. The first material may be bonded to the main body and positioned toward a first edge thereof. The second material may be bonded to the main body and positioned toward a second edge thereof. The second edge may be positioned opposite the first edge such that the first and second materials are positioned toward opposite edges of the main body. At least one of the first material or the second material may include a first reactive material of a chemically reactive two-part cure system that is configured to chemically react upon contact of the first reactive material with a second reactive material of the chemically reactive two-part cure system.

Abstract: Thin film photovoltaic devices that include at least one lead bar extending through a connection aperture defined in the encapsulation substrate are provided. The photovoltaic device can include: a transparent substrate; a plurality of photovoltaic cells on the transparent substrate; a first conductive ribbon electrically connected to a first photovoltaic cell; an encapsulation substrate laminated to the transparent substrate such that the plurality of photovoltaic cells and the conductive ribbon are positioned between the transparent substrate and the encapsulation substrate; and, a first lead bar extending through a first connection aperture defined in the encapsulation substrate. The first lead bar is electrically connected to the first conductive ribbon. For example, a meltable conductive material can be connected to the first lead bar and to the first conductive ribbon to establish an electrical connection therebetween.

Abstract: Thin film photovoltaic devices that include a direct connection to at least one lead bar extending through a connection aperture defined in the encapsulation substrate to electrically connect to an underlying conductive ribbon are provided. The photovoltaic device can include: a transparent substrate; a plurality of photovoltaic cells; a conductive ribbon electrically connected to a photovoltaic cell; an encapsulation substrate laminated to the transparent substrate such that the plurality of photovoltaic cells and the conductive ribbon are positioned between the transparent substrate and the encapsulation substrate; and a lead bar extending through a connection aperture defined in the encapsulation substrate and electrically connected to the conductive ribbon. The lead bar can define a lead tab that establishes a mechanical connection having a biasing force between the lead bar and the conductive ribbon.
