ABSTRACT An improved current collection structure for a photovoltaic device. The current collection structure is especially useful for large area photovoltaic devices. Such devices include a substrate a semiconductor body on the substrate a transparent electrically conductive layer on the semiconductor body and a bus grid structure in electrical contact with the conducting layer for collecting and carrying current generated by the photovoltaic device. The structure includes a plurality of grid fingers electrically resistively interconnected to a busbar to reduce the effect of current flowing through low resistance defects in the device. The structure may also include an insulator interposed between busbar and the conductive layer . The resistive interconnections may be fusible links . The conductive layer may have a relatively high sheet resistance and the current collecting fingers may have varying cross sectional areas to provide substantially equal resistances for fingers of different lengths. All of these features thwart the effects of low resistance defects in the photovoltaic device.
