Cheaper panels by David Flint

Most solar panels include a layer of cadmium chloride which greatly increases the efficiency of the active component - cadmium Telluride. Unfortunately cadmium chloride is both toxic and expensive, requiring elaborate safety precautions during manufacture.

Happily Dr Jon Major of Liverpool University has found that we can use magnesium chloride instead. It works just as well, is safe and costs less than 1% of the price!

Another boost for solar PV.
