Color-coded patterns for epitaxial lift-off (elo) films background

Abstract

The present disclosure provides a photovoltaic device formed according to a color code scheme and methods of manufacturing thereof. In an example, the photovoltaic device may include one or more photovoltaic cells formed according to one or more applications of the photovoltaic cells. The photovoltaic device may also include a rear contact layer formed on a rear surface of the one or more photovoltaic cells, the rear contact layer including one or both of a composition or a thickness configured to produce a unique color code in the color code scheme that is visible in areas of the photovoltaic device outside of areas covered by the photovoltaic cells and corresponding to the particular product configuration of the photovoltaic device. The photovoltaic device may also include a back reflector formed on a rear surface of the rear contact layer.
