Uranium Oxide Solar Panels

Did you know that uranium dioxide is a semiconductor? In fact, it’s a really good one! That means that you could make solar panels, LEDs, and computer chips from it…can you imagine uranium oxide solar panels?

    A good material to make solar panels. There is a lot of DU around.

    DU an also be used as a catalyst for destruction of certain air pollutants. Uranium oxides are known to have high efficiency and long-term stability when used to destroy volatile organic compounds (VOCs) when compared with some of the commercial catalysts, such as precious metals, TiO2, and Co3O4 catalysts.

    Well, I'm not a semiconductor engineer, but AFAIK usable semiconductors need good electron mobility.. and as far as I googled, uranium oxide's is rottenly sluggish compared to f.ex. silicon.

    Urania (uranium dioxide) is used as the insulating layer of a CMOS device (complimentary metal oxide semiconductor). CMOS devices are very low power and high efficiency. Urania solar cells have five peaks within the visible light spectrum photoreactive spectrum compared to a single peak for today's solar cells. Based on research that has already been done at Oak Ridge urania solar cells should have between three and five times more efficiency — more electricity produced for a given light input.

    Urania CMOS devices also tolerate much higher temperatures thus needing far less cooling. High electrical output together with high temp tolerance means that concentrating mirrors or lenses can be used to reduce the size of a solar panel for a given output. The increased efficiency per square meter is sufficient to make possible true solar powered cars and houses.

    What about the toxicity of uranium dioxide? I'm not an expert, and perhaps I need to read more, but any electronic device has a lifetime and will need to handled correctly at the end of the product's life. Yes, uranium oxide solar panels and integrated circuits could use much of the material that exists today but isn't it just delaying the management of such materials?

    The toxicity of all semiconductor materials used in solar panels is a concern. Uranium oxide would not be unique in this regard.

    Can urainum be used to power a solar panel?
