Solar cells are made from silicon metal. Refining pure metals requires a lot of energy and this comes from burning fossil fuels. Smelting metals is often an environmentally dirty process too.

As the last answerer said, production involves metals. And depending on the cells, some solid state electronics components also use arsenic, cadnium, and other highly toxic materials.
