Dye sensitised solar cells get another boost in efficiency

Dye-sensitised solar cells can be improved by a new dye formulation, according to researchers at Swiss institution EPFL, where such cells were invented by Brian O’Regan and Michael Grätzel  in 1991. Dan Zhang and Marko Stojanovic in Grätzel’s have developed a dye (combining a carrier donor and acceptor) called MS5 that can increase open circuit ...
