We propose fabricating all-metal-oxide photovoltaic devices using materials that are abundant in the Martian regolith. The long-range goal of this investigation is to develop a method for fabricating photovoltaic devices using minimally-processed in-situ resources available on Mars and fabrication techniques amenable to the Martian environment to support NASA’s mission goals. To achieve our long-range goal, we are fabricating and characterizing p-n homojunction photovoltaic devices using hematite (α-Fe2O3) as the n-type semiconductor substrate and a recently discovered Fe0.84Cr1.0Al0.16O3 metal-oxide alloy as the p-type semiconductor substrate.  Hematite and the elements Fe, Cr, and Al are all abundant in the Martian regolith and will serve as the light-absorbing layers in the p-n homojunction photovoltaic devices.
