Switching to solids: Solid-state dye-sensitized solar cells are achieving efficiencies similar to those of their counterparts with liquid electrolytes. The new p-type semiconductor CsSnI3 was found to be an excellent replacement for the traditional I/I3 redox system. The picture shows a cross section of a dye-sensitized solar cell based on CsSnI3.
