Abstract
A photovoltaic module comprises a back substrate having a plurality of conductive interconnects on top thereof. A conductive interconnect includes a first contact region and a second contact region. The photovoltaic module further comprises a plurality of photovoltaic cells comprising front electrodes disposed on a front surface of a photovoltaic layer on top of back electrodes on top of a support substrate. A plurality of back vias extending through the support substrate of a first cell form an electrical contact between the back electrodes and the second contact region, and a plurality of front vias extending through the support substrate, the back electrodes and the photovoltaic layer of a second cell form an electrical contact between the front electrodes and the first contact region, and is insulated from an electrical contact with the back electrodes and a P side of the photovoltaic layer.
