透明的太阳能收集表面是一种令人兴奋的新方法，可以在建筑物和移动电子设备周围收集太阳能，在不影响外观的情况下提高它们的效率和自主性。最近展示的紫外线(UV)和近红外(NIR)选择性光收集器使透明发光太阳能聚光器(LSC)具有无与伦比的可扩展性、灵活性、美观质量和价格。因此，在这些新系统中出现了效率限制的问题。从这个角度，回顾了这些集中器系统的理论效率极限，并概述了接近这些极限的实际考虑。对于UV和UV/NIR选择收获，单结透明LSC的热力学限制为21%，而在具有光捕获功能的全透明多面板器件中，这一比例增加到35%以上。在得出这些限制的过程中，确定了关键的材料和工程挑战，以充分优化能够推动它们走向商业现实的透明太阳能聚光器。
Visibly transparent solar harvesting surfaces are an exciting new approach to harvesting solar energy around buildings and mobile electronics to improve their efficiency and autonomy without impacting their appearance. The recent demonstration of ultraviolet (UV) and near‐infrared (NIR) selective light harvesters have enabled transparent luminescent solar concentrators (LSCs) that boast unparalleled scalability, flexibility, aesthetic quality, and affordability. Consequently, the question of the efficiency limits has emerged in these new systems. In this perspective, the theoretical efficiency limits of these concentrator systems are reviewed and practical considerations are outlined to approach these limits. For UV and UV/NIR selective harvesting single‐junction transparent LSCs are constrained thermodynamically to 21%, which increases to over 35% in fully transparent multipanel devices with light trapping. In deriving these limits, key material and engineering challenges are identified to fully optimize transparent solar concentrators that can push them towards commercial reality.
