A polymer‐embedded dendritic, bodipy‐based panchromatic absorber with a built‐in energy gradient concentrates incident solar radiation at a terminal chromophore, resulting in a monochromatized emission directed to the sides of the polymer waveguide (see picture). This particular design minimizes self‐absorption losses from the peripheral antenna units with an impressive S factor of 10 000.
