Technological relevance and photovoltaic production potential of high-quality silica deposits on Mars

Harvesting solar energy is indispensable to meet the power needs of future Mars exploration and habitation missions. Space photovoltaic power is a proven technology with 60 years of significant advancements compared to space nuclear power, which is yet to be proven for high-power applications. We have studied the relative abundance, spatial distribution, and technologic applications of high-silica deposits on Mars in this context. After investigating the expected performance of Si solar cells on Mars, the in situ manufacturing possibilities of such solar cells on Mars will be then explained. The presence of widely distributed (extended up to the southern polar region) and significant silica deposits on Mars supports the extensive use of silicon solar power on this planet in the future.
