超高聚光光伏系统旨在提高太阳光的转换效率并降低电力成本。然而，仍然需要开发具有更高效率和角度公差的光学系统，以使其成为现实。这封信提出了一种新颖的设计，能够实现4096×的几何浓度。该系统由四个基于抛物面镜和光导的聚光器单元组成，它们将太阳光集中到单个电池上。此外，还为验证目的组装了一个初步的概念验证模块。新的设计超过了现有系统的光学效率，84%，并提供了几乎两倍的接受角，0.6度。
Ultra-high concentrator photovoltaic systems aim to enhance the conversion efficiency of sunlight and to reduce the cost of electricity. However, it is still necessary to develop optical systems with higher efficiencies and angular tolerances for them to become a reality. This Letter proposes a novel design that is able to achieve a geometric concentration of 4096×. The system consists of four concentrator units based on parabolic mirrors and optical guides that concentrate the sunlight onto a single cell. Additionally, a preliminary proof-of-concept module has been assembled for validation purposes. The novel design exceeds the optical efficiency of the existing systems, ≈84%, and offers almost double acceptance angles, ≈0.6∘.
