Abstract
A thin film photovoltaic device includes a substrate and a first conductive layer coupled to the substrate. The first conductive layer includes at least one first groove extending through a first portion of the first conductive layer to a portion of the substrate. The device also includes at least one semiconductor layer coupled to a remaining portion of the first conductive layer and the portion of the substrate. The at least one semiconductor layer includes a plurality of non-overlapping vias, each via extending through a portion of the at least one semiconductor layer to a portion of the first conductive layer. The device further includes a second conductive layer coupled to a remaining portion of the at least one semiconductor layer and portions of the first conductive layer. The second conductive layer includes at least one second groove extending through a portion of the second conductive layer to a portion of the at least one semiconductor layer.
