On the Ability of Förster Resonance Energy Transfer to Enhance Luminescent Solar Concentrator Efficiency

摘要: Developing means to reduce the cost of solar energy is vital curb our carbon footprint over upcoming decades. A luminescent concentrator (LSC) a potential solution as it provides light concentration without any tracking device and can be readily integrated into built environment. In this study we report on an advanced LSC design that employs quantum dots absorption fluorophores organic dye molecules emission fluorophores. By linking two types each other, transferred efficiently via Forster resonance transfer (FRET) from dot molecule. This novel method makes use dot's spectrally wide profile higher yield dye. We show overcome losses normally incurred due low emitter by transferring absorbed linked fluorophore with yield. Our experimental measurements FRET enhance optical efficiency at least 24.7%. The maximum theoretical has been investigated ray-tracing found 75.1%; represents relative improvement even 215.5% compared doped only (23.8%), showing great concept. will initiate interest in which have not considered for applications thus far because their or small Stokes shift.
