Northwestern University researchers have developed a new solar cell that, in principle, will minimize solar energy technology limitations like high production cost, low operating efficiency and durability. Also, many current cells rely on toxic and scarce materials.
In the Northwestern cell, a thin-film compound made up of cesium, tin and iodine, called CsSnI3, replaces the entire liquid electrolyte of the Grätzel cell. Details of the new solar cell -- an efficient, more stable and longer lasting cell -- will be published May 24 by the journal Nature.
