    摘要: Tie layers and structures that exhibit superior properties and that provide desirable optical properties when incorporated into laminates, such as windshields, windows or other glazings containing a holographic optical element (HOE) are disclosed. The tie layers, when used in a laminate in conjunction with the HOE film, optionally with additional polymer layers, maintain and do not detract from the HOE film properties.

    摘要: An electrochromic device is disclosed. The electrochromic device includes (i) a first substrate with an electrically conductive layer on an inner surface thereof; (ii) a second substrate with an electrically conductive layer on an inner surface thereof; (iii) an electrochromic assembly comprising at least one electrochromic layer; (iv) a first bus bar pair comprising a positive bus bar electrically connected to the electrically conductive layer of the first substrate and a negative bus bar electrically connected to the electrically conductive layer of said second substrate; and (v) a second bus bar pair including a positive bus bar electrically connected to the electrically conductive layer of the first substrate and a negative bus bar electrically connected to the electrically conductive layer of the second substrate. A process for reversibly changing the optical properties of an electrochromic device that includes at least one electrochromic layer is also described.

    摘要: The present invention provides a photovoltaic device comprising metal and a polyvinyl butyral) layer that incorporates a suitable amount of 1 H- benzotriazole. When electrical bias is applied to the photovoltaic device, 1 H- benzotriazole forms a barrier layer at the metal/poly(vinyl butyral) interface, which, for example, unexpectedly virtually eliminated the yellowing of polyvinyl butyral) in photovoltaic devices comprising silver components.
