Researchers at Julius-Maximilians-Universität Würzburg have developed an innovative light-harvesting system named URPB, which mimics the efficiency of natural light-collecting antennae found in plants and bacteria. The system consists of four different merocyanine dyes stacked closely together to enable efficient energy transport. Unlike traditional systems, URPB absorbs light across the entire visible spectrum, similar to inorganic semiconductors, while maintaining the high absorption coefficients of organic dyes. This allows the system to absorb a significant amount of light energy in a thin layer, enhancing its efficiency. The researchers demonstrated that URPB converts 38% of the irradiated light energy into fluorescence, a substantial improvement over individual dyes. The innovative arrangement and combination of dye molecules in the system play a crucial role in its performance. The study was published in the journal Chem and offers promising advancements in solar technology by addressing the limitations of current light-harvesting systems.
