PHOTOVOLTAICS WITH INTERFEROMETRIC RIBBON MASKS

摘要

An interferometric mask covers reflective conductors on the back side of a photovoltaic device. Such an interferometric mask may reduce reflections of incident light from the conductors. In various embodiments, the mask reduces reflections, so that a front and back electrode pattern appears black or similar in color to surrounding features of the device. In other embodiments, the mask may modulate reflections of light such that the electrode pattern matches a color in the visible spectrum.
