An optically enhanced architecture can be used to fabricate high-performance polymer solar cells. The basic optical parameters that control light propagation in a layered device are such that an optimal light harvesting is achieved. The general character of such optically enhanced architecture is demonstrated by applying it to two different kinds of low bandgap polymers.
