Traditional solar panels reach 40% efficiency but require heavy, expensive materials. Researcher Felix Lang notes they come with a hefty cost in space missions.

By melting anorthositic Moon dust into moonglass, Lang’s team created a substrate for solar panels. This innovation could reduce launch mass by 99.4%—a potential game-changer.

Pairing perovskite with moonglass, researchers created ultra-light, energy-rich solar cells. They produce 100x more energy per gram than Earth-based systems.

Unlike conventional glass, moonglass is already brown-tinted from Moon dust impurities—helping it resist space radiation and avoid the darkening that ruins traditional cells.

Perovskite processing solvents may not work on the Moon. Researchers face tough chemistry challenges but aim to test fixes in an upcoming demo mission.

Moon’s lower gravity may alter how moonglass forms. Its impact on transparency and structure remains a wild card as fabrication tech evolves.

Temperature swings from +100°C to -170°C could threaten long-term cell stability. Yet, scientists believe moonglass offers a tough, adaptive material.

Lang envisions lunar cities powered by native dust. “We can now turn it into solar cells,” he says—unlocking a cleaner, leaner path to off-Earth infrastructure.
