Perhaps the most interesting recent use of magnesium chloride is in experimental solar cells. The most common form of cell at the moment makes use of heavy, inflexible silicon panels, but there are a range of cells available that instead are based on a flexible film that can be as thin as a single micrometre.

Current thin film cells replace silicon with cadmium telluride, which is then coated with a layer of cadmium chloride, a compound that boosts its otherwise relatively poor efficiency to be comparable with silicon. Unfortunately this is not a substance that is ideal to use, as it is hazardous during manufacture, and when spread across the countryside in solar panels it is water soluble, toxic and can cause significant damage to aquatic life.

It might seem at first sight that magnesium chloride is a bit of an inorganic wallflower, a compound that is limited to dull applications like de-icing. But with excellent green credentials and a role in making tofu, it should really be the darling of the environmentally conscious consumer.
