Non-critical, non-toxic solar panels

The UNSW School of Photovoltaic and Renewable Energy Engineering, have achieved the world's highest efficiency rating for a full-sized thin-film solar cell using a competing thin-film technology, known as CZTS. Unlike its thin-film competitors, CZTS cells are made from abundant materials: copper, zinc, tin and sulphur. And CZTS has none of the toxicity problems of its two thin-film rivals, known as CdTe (cadmium-telluride) and CIGS (copper-indium-gallium-selenide). CZTS is cheaper and easier to bring from lab to commercialisation than other thin-film solar cells, given already available commercialised manufacturing methods.
