This work describes a method for limiting internal losses of a luminescent solar concentrator (LSC) due to reabsorption through patterning the fluorescent dye doped coating of the LSC. By engineering the dye coating into regular line patterns with fill factors ranging from 20 - 80%, the surface coverage of the dye molecules were reduced, thereby decreasing the probability of the re-emitted light encountering another dye molecule and the probability of reabsorption. Two types of fluorescent dyes with different quantum yields were used to examine the effects of patterning on LSC performance. The effect of various dimension and geometry of the patterns on the efficiency and edge emission of LSC are presented and analyzed.
这项工作描述了一种通过对发光太阳能聚光器（LSC）的荧光染料掺杂涂层进行图案化来限制其内部因再吸收而产生的损失的方法。通过将染料涂层设计成填充因子在20%至80%之间的规则线条图案，染料分子的表面覆盖率降低，从而降低了重新发射的光遇到另一个染料分子的概率以及再吸收的概率。使用两种具有不同量子产率的荧光染料来研究图案化对LSC性能的影响。展示并分析了图案的各种尺寸和几何形状对LSC效率和边缘发射的影响。
