| Popis: |
We have fabricated a functional prototype of an ultralight power converter tile; a modular building block for a space-based solar power system. The tile is $\sim 10\mathrm \times 15$ cm in area, and weighs $\sim 1.5$ kg/$\text{m}^{\mathbf {2}}$. It comprises a photovoltaic (PV) solar energy collector, a radio-frequency (RF) power converter, and an array of transmission antennas. The PV collector subassembly utilizes $\sim 15\mathrm {x}$, 1D parabolic trough reflective concentrators with triple-junction (3J) solar cells. It has areal mass of $\sim 0.8$ kg/$\textbf{m}^{\mathbf {2}}$, 74% optical efficiency, and a peak specific power of $\sim 230\mathrm {W} /$kg. We demonstrated wireless power transmission over a distance of $\sim 50$ cm in our lab. Analysis of the sources of mass and inefficiency suggest a path towards achieving dramatically higher performance with future designs. |
