Original Solar Cell Inventor Scores $1.07M Millennium Prize

Tiffany Kaiser

Scientist and professor of photonics and interfaces at the École Polytechnique Fédérale de Lausanne in Switzerland, Michael Graetzel, won the Millennium Technology Prize of $1.07 million for his dye-sensitized solar cells, also known as "Graetzel cells."

These new dye-sensitized solar cells are low in cost, and can work on a broad scale. Graetzel cells do not require a large setup to manufacture, they should be considerably less expensive than solid-state cell designs in bulk, they're mechanically robust and can be engineered into flexible sheets. They also require no protection from minor elements such as tree strikes or hail.
