Novel findings from the Universities of Surrey and Swansea indicate that it is indeed possible to manufacture economically viable, lightweight solar panels capable of generating electricity in the extraterrestrial environment.
Distinguished as the inaugural endeavor of its kind, this study, spanning six years and encompassing 30,000 orbits, scrutinized the power-generation capability and resilience to solar radiation exhibited by these panels. These invaluable insights may pave the way for the establishment of economically feasible solar farms in space.
Advancements in Solar Cell Technology
Professor Craig Underwood, Emeritus Professor of Spacecraft Engineering at the Surrey Space Centre, University of Surrey, expressed his satisfaction: “We are exceedingly pleased that a mission originally intended for a one-year duration has endured for six years. The meticulous data analysis confirms the panels’ remarkable resistance to radiation and the preservation of their thin-film structure in the challenging thermal and vacuum conditions of space. This ultralight solar cell technology holds the potential to enable the construction of expansive, cost-effective solar power stations positioned in space, thereby ushering clean energy back to Earth. We now possess the inaugural empirical evidence of the technology’s reliability in orbit.”
Researchers from the University of Swansea’s Centre for Solar Energy Research innovatively crafted solar cells using cadmium telluride. These panels boast a larger surface area, reduced mass, and significantly enhanced power output compared to existing technology, all while being relatively cost-effective to manufacture.
The University of Surrey’s scientists devised instruments to assess their performance during orbital operation. The satellite itself was developed and constructed at the Surrey Space Centre in collaboration with a team of aspiring engineers from the Algerian Space Agency (ASAL).
Potential for Commercial Viability
While the power efficiency of these cells exhibited a gradual decline over time, the research community contends that their findings validate the functionality of solar power satellites and suggest their potential commercial viability.
Dr. Dan Lamb from the University of Swansea emphasized, “The successful in-orbit evaluation of this innovative thin-film solar cell payload has attracted additional funding opportunities for the further advancement of this technology. Large-scale solar arrays for space applications constitute a rapidly expanding market, and demonstrations like this contribute to bolstering the UK’s esteemed reputation in space technology.”
