Solar panels from Moon Dust can cause a revolution in Lunar Energy Supply
In an important progress for the durability of the moon, scientists have manufactured solar cells with the help of simulated moon fabric, and offer a lightweight, radiation -resistant energy source for future moon missions. The research, published on 3 April in Device, a diary of Cell Press, outlines a new approach that can drastically reduce the need to drastically reduce the earth’s extensive materials.
“Current space quality solar cells can achieve 30% to 40% efficiency, but they have substantial costs in both dollars and mass,” explains Felix Lang of the University of Potsdam. “These cells rely on heavy glass or thick films, and the costs of launching them in a job is considerable.”
Lang and his team propose to bypass these limitations by buying materials directly from the moon. Their concept replaces terrestrial glass by Moonglass-Glas made from Lunar Regolith. According to their calculations, this switch could lower the loading mass of a mission to 99.4% and reduce related transport costs by 99%, which releases the road for scalable energy infrastructure on the moon surface.
To test their hypothesis, the researchers melted a synthetic version of Moon Dust to create Moonglass and then used it as the basis for solar panels built with perovskiet crystals. These materials are known for their low costs, convenience of production and strong conversion possibilities of solar-to-electricity. The resulting panels surpassed conventional in energy output per gram and deliver up to 100 times more energy for each unit of mass implemented.
“If you can reduce the weight by 99%, ultra-efficient 30% cells are no longer a required U can simply produce more on the moon,” said Lang. “And our prototypes are also more resilient for radiation, in contrast to conventional cells that break down over time.”
The team subject the new solar cells to radiation levels that are typical of space environments. The results were promising: while standard glass gets darker with exposure-hindered light transmission and efficiency moonglass retains its performance. The natural impurities give it a brown hue that opposes further discoloration and the material stabilizes radiation damage.
The manufacture of Moonglass turned out to be easy. The process does not require complex purification steps and the high temperatures required for melts can be achieved using concentrated sunlight and an abundant resource on the moon. With careful adjustments to the glass thickness and the internal structure of the solar cell, the team achieved 10% efficiency. They project that more transparent Moonglass could increase this to 23%.
Nevertheless, the production of Lunar forms unique obstacles. The low gravity of the moon can change how melted regolite solidifies. Existing perovskiet processing techniques depend on solvents that evaporate poorly in a vacuum. In addition, extreme temperature fluctuations threaten material stability. To tackle these variables, the researchers are planning to launch a small demonstration on the moon, where their solar cells can be tested under actual moon conditions.
“From building structures to extracting fuel, moon fabric becomes a versatile tool for future missions,” noted for a long time. “Now we may also be able to turn into solar cells and lay the foundation for a self -sufficient moon base.”
