Abstract
Light management plays a significant role for every optoelectronic device, as the spectral management and control over the directionality (or étendue) of light ultimately defines the efficiency. Here, demonstrate this design principle by exploring how luminescent concentrators, a class of concentrators that use downshifting and guiding of light, could be used to create high efficiency, spectrum-splitting solar modules. First, we use probabilistic modeling and modified detailed balance calculations to quantify the required material properties. We show that >50% efficiency modules are possible with realistic materials, but these designs require high (>80%) collection efficiency of photoluminescence, which is not possible with traditional LSC designs. Second, we then demonstrated one way to improve the collection efficiency through using spectrally selective filters. Utilizing an entirely solution processed design, we fabricated perovskite nanocrystal luminescent concentrators with improved photoluminescence trapping.
