可视透明发光太阳能聚光器(TLSC)可以将现有的窗玻璃系统和非窗面转化为太阳能集热资源，显著提高能源利用效率。虽然人们对提高功率转换效率有很大的兴趣，但很少有人关注将发光太阳能聚光器(LSC)集成到非窗口表面或具有显著红外吸收系数的窗口的挑战。在这些情况下，当LSC直接无缝地集成到对红外光具有高度吸收或散射的表面时，可以有效地禁用全内反射(TIR)。为了克服这一挑战，我们在TLSC波导和背面之间使用了一种具有高透明度的低折射率胶粘剂薄膜，以保持器件的功能性和底层表面的美观质量。光伏测量表明，这种结构的存在重新启用了TIR。因此，这种方法可以有效地提高LSC的性能和可扩展性，并允许TLSC集成到汽车、广告牌和建筑物等任意表面上。
Visibly transparent luminescent solar concentrators (TLSCs) can convert existing window glazing systems and non-window surfaces into solar energy harvesting resources, dramatically improving energy utilization efficiency. While there has been a significant interest in improving the power conversion efficiency, little attention has been focused on the challenges of integrating luminescent solar concentrators (LSCs) onto non-window surfaces or windows with significant infrared absorption coefficients. In these situations, the total internal reflection (TIR) can be effectively disabled when LSCs are directly and seamlessly integrated onto surfaces that are highly absorptive or scattering to infrared light. To overcome this challenge, we utilize a low refractive index adhesive film with high transparency between the TLSC waveguide and the back surface, to maintain both the device functionality and aesthetic quality of the surface underneath. Photovoltaic measurements were conducted to show that the TIR is re-enabled with the presence of such a structure. Thus, this method can effectively improve LSC performance and scalability, and allows TLSCs to be integrated onto arbitrary surfaces such as automobiles, billboards, and buildings.
