A startup from Luxemburg, called Maana Electric, recently developed a fully automated solar panel factory called TerraBox, which requires only sand and electricity. They even got SpaceStarters reward.
Well, I couldn't find that information, so I guess it's a business secret.
It can literally use any type of sand found on Earth or on Mars to create solar panels. It's 100% clean, unlike the conventional solar panel producing systems, which "produce more CO2 per kWh than where we need to be by 2040 to stop global warming". It's light and it produces oxygen as a byproduct, so the astronauts can use it for breathing.
The company focused on using the most out of the harshest conditions on Earth and beyond. Their plan is to 1) curbe Global Warming, 2) conquer space and test this product on Moon, Mars and beyond.
