We present a customizable technique of coloring photovoltaic modules by laminating colored textiles onto photovoltaic cover glass (CoTex). A white nonwoven fabric is imprinted with any color, design or graphic and is then laminated onto an arbitrary, frameless photovoltaic module. The short-circuit current losses of these modules range from 12% to 32% and depends on the color and its coverage, i.e. how much of the solar cell structure remains visible. We fabricate CoTex test modules in cyan, magenta and yellow with different print coverages to experimentally analyze their external quantum efficiency, reflection spectrum, energy yield, and appearance. These experiments on the three basic colors forms the basis for using digital prototypes that predict the energy yield and the printing parameters for arbitrary colors.
