Researchers find they can replace expensive, toxic metal with this cheap food additive.

In solar cell manufacturing, expensive toxic metal cadmium chloride that is difficult to handle and dispose of, can be replaced by common food additive that is 30 times cheaper. The switch has no effect on efficiency of the solar cells and moreover is simple to implement by a quick substitution of salts in current manufacturing processes.

Solar cell usage grew by 76% in 2012, helped by improving technology and the entrant of low cost manufacturers from China. With ever-increasing improvements to the market like these, solar energy could one day be widely available and cost effective.
