*** 96-60727 Ham This Small Business Innovation Research Phase I project will synthesize and test new polymer materials for application in luminescent solar concentrators (LSC's). LSC's use a large area sheet to absorb solar radiation and light-pipe fluorescence efficiently to solar photovoltaic cells on the much smaller edge area. Thus, expensive solar cells can produce several times more electric power by using inexpensive plastic or glass sheets. LSC's work well in diffuse sunlight, do not need to track the sun, dissipate excess energy, and shift light toward the red where solar cells are more efficient. LSC's have been demonstrated to provide efficient energy converters but cannot be implemented because no suitable fluorescent materials (e.g. dyes in plastics) have been identified that do not bleach for long enough times to be cost effective. This firm has identified specific materials that should have the performance required for LSC.s to achieve competitive, levelized costs and proposes to prepare and test these novel materials . This project will prepare polymer materials and measure their absorption and fluorescence spectra and their fluorescence quantum efficiencies. This firm will obtain preliminary longevity data for these materials using an accelerated weathering tester. These results will be used in a preliminary economic analysis to determine the feasibility of our approach. *** ??

这个小企业创新研究一期项目将合成和测试用于发光太阳能聚光器（LSC）的新型聚合物材料。LSC使用大面积的薄片来吸收太阳辐射，并将荧光有效地输送到太阳能光伏电池较小的边缘区域。因此，昂贵的太阳能电池可以使用便宜的塑料或玻璃片产生几倍以上的电力。LSC在漫射阳光下工作得很好，不需要跟踪太阳，消散多余的能量，并将光转向红色，太阳能电池效率更高。LSC已被证明可以提供高效的能量转换器，但无法实施，因为没有找到合适的荧光材料（例如塑料中的染料）不会漂白足够长的时间，从而具有成本效益。这家公司已经确定了应该具有LSC所需性能的特定材料。S以达到有竞争力的，平衡的成本，并建议准备和测试这些新材料。本项目将制备高分子材料并测量其吸收光谱和荧光光谱及其荧光量子效率。该公司将使用加速老化试验机获得这些材料的初步寿命数据。这些结果将用于初步的经济分析，以确定我们的方法的可行性。* * * ? ?
