摘要

聚光光伏(CPV)可以提高空间光伏发电效率，降低空间光伏发电成本。我们介绍了一种基于转移印刷微型太阳能电池阵列的新型单片、超薄、轻量化CPV范式。在我们的反射设计中，微单元阵列嵌入在耐辐射玻璃光学器件中，具有83%的光学效率和$\pm mathbf{77} ^{circ}$接收角，几何增益$32 \倍$。该系统厚度小于1毫米，使用最先进的三结微电池，能够实现352 W/kg的比功率密度。

Lightweight Monolithic Microcell CPV for Space

Concentrating photovoltaics (CPV) can increase the efficiency and reduce the cost of photovoltaic power in space. We introduce a new monolithic, ultrathin, and lightweight CPV paradigm based on a transfer-printed microscale solar cell array. In our reflective design, the microcell array is embedded in a radiation-tolerant glass optic that delivers 83% optical efficiency with a $\pm mathbf{77} ^{circ}$ acceptance angle at $32 \times$ geometric gain. The system is $<1$ mm thick and capable of achieving a specific power density of 352 W/kg using state-of-the-art triple junction microcells.
