THIN-FILM DEVICE WITH ELECTRICAL ISOLATION LAYER

A photovoltaic apparatus is provided including a front sheet, a back sheet, and a photovoltaic device disposed between the front sheet and the back sheet. The photovoltaic device includes a first photovoltaic cell and a second photovoltaic cell separated in a first direction. The photovoltaic device further includes a first serial interconnect having a length that extends in a second direction. The first serial interconnect is disposed between the first photovoltaic cell from the second photovoltaic cell. The first photovoltaic cell and the second photovoltaic cell are electrically connected in series by the first interconnect. The photovoltaic apparatus further includes a spacing layer including a first roving disposed between the first interconnect and the back sheet. The first roving has a length that is aligned with the length of first serial interconnect.
