With patented technology and customer traction in a booming sector, Extraterrestrial Power is ready to take off and manufacture solar cells for customers worldwide, and beyond Earth!
Delivering affordable power to humanity in space.
Extraterrestrial Power develops highly efficient, mass-manufacturable, and radiation-tolerant solar cells designed to drastically reduce the cost of power in space.
-
By applying space-grade rigour to the more affordable method of mass-production used to make terrestrial solar cells, ETP has succeeded in thinning out space solar cells to a level where they can be mass-produced alongside terrestrial ones, while maintaining their space-grade efficiency and stability.
-
Traditional space solar cells use rare and expensive materials (typically Gallium Arsenide) and are reinforced through an expensive, low-volume manufacturing process – resulting in high costs, supply chain bottlenecks, and delays.
By adapting silicon cells, ETP can supply in weeks rather than years. The product is 10 times cheaper and 1000 times more cells.
