Luminescent solar concentrators based on molecular dyes are a promising approach to light collection for photovoltaics owing to their potential low cost and wide light acceptance angles. However, they readily suffer from self-absorption, which rapidly reduces device efficiency. We use a perylene-based sensitizer–emitter system to reduce self-absorption. The sensitizer and emitter are copolymerized to enhance energy transfer to the emitter. The sensitizer is susceptible to yield-reducing H-aggregation. We show that a composite polymer can be used to reduce H-aggregation, while maintaining efficient energy transfer.

具有per生色团的聚合物复合材料中能量转移的优化

基于分子染料的发光太阳能聚光器由于其潜在的低成本和宽广的受光角度，是一种有前途的光伏光收集方法。然而，它们容易遭受自吸收，这会迅速降低器件效率。我们使用基于ylene的敏化剂-发射体系统来减少自身吸收。敏化剂和发射体共聚以增强向发射体的能量转移。敏化剂易于降低产率的H聚集。我们表明，复合聚合物可用于减少H的聚集，同时保持有效的能量传递。
