A feature on this evening’s which can reduce the cost and toxicity of cadmium telurite PV cells. Apparently cadmium chloride is an essential element to make the cell work … but researchers from Liverpool University have discovered that magnesium chloride can be substituted with no reduction in efficiency. Cadmium telluride cells in themselves are, apparently, a

There is surprising – even shocking – good news: Our ability to convert sunshine into usable energy has become much cheaper far more rapidly than anyone had predicted. The cost of electricity from photovoltaic, or PV, solar cells is now equal to or less than the cost of electricity from other sources powering electric grids
