DIRECT CONNECTION OF LEAD BAR TO CONDUCTIVE RIBBON IN A THIN FILM PHOTOVOLTAIC DEVICE

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.
