摘要:
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. Methods are also provided for electrically connecting at least one lead to a thin film photovoltaic device.

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. Methods are also provided for electrically connecting a lead to a thin film photovoltaic device.
