Abstract

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.
