Moon Dust Substrate For Solar Panels

Simulated moon dust has been used to make the substrate of a solar cell, according to University of Houston researchers. The fine grey powder is 50% silicon dioxide, along with a mixture of oxides of twelve different metals (including aluminum, magnesium and iron).


(Regolith in cross-section)

Alex Freundlich and his colleagues melted JSC-1, a powder that simulates the lunar regolith samples brought back by Apollo astronauts, in a vacuum. The melted powder solidifies into a smooth, glassy sheet on which solar cells may be deposited by thermal evaporation. The finished cell can then convert sunlight into electricity.

The simulated lunar solar panels are only about one percent efficient in converting sunlight to electricity (conventional cells convert about twenty percent).

In his 1951 novel The Moon is Hell, John W. Campbell wrote about marooned members of the second lunar expedition surviving by manufacturing solar cells using lunar materials.
