Silicon solar cells are not the only type of solar cells available to capture the sunlight, we also have dye-sensitized solar cells also called Grätzel cells after their inventor, Michael Grätzel. I’m glad to announce you that a team of researchers from China and Switzerland have reported the highest efficiency for dye-sensitized solar cells which could make solar power the primary energy source in the future.

Grätzel cells are made of titanium dioxide and powerful light-harvesting dyes, you can make flexible sheets or coatings out of them, and they have the advantage of being cheaper than silicon solar cells. The problem with dye-sensitized cells is that they are not very efficient…
