title: The 2010 millennium technology grand prize: dye-sensitized solar cells.
abstract: The 2010 Millennium Technology Grand Prize was awarded to Michael Gratzel for his ground-breaking research that has led to the practical application of dye-sensitized solar cells. Although Gratzel began his research well before nanotechnology had the "buzz" that it does today, the mesoscopic thin films he has developed have paved the way for generations of scientists to exploit the nanoscale for energy conversion. In addition to practical application, his research has led to a deeper understanding of photoinitiated charge-transfer processes at semiconductor interfaces. Here, the key scientific developments that guided early progress in dye-sensitized solar cells are summarized, with emphasis on fundamental advances that have enabled practical application.
