Solid State Solar Cell

May-28-12 Researchers have developed new, solid-state solar cell that solves the leaking problems common with the promising, yet somewhat flawed Grätzel cell design.

The new thin-film compound, CsSnI3, is made of a combination of cesium, tin, and iodine. When added in liquid form to the dye-coated nanoparticles packed inside the solar cells, the solvent evaporates and leaves a solid mass behind, replacing the liquid electrolyte of the Grätzel cells and creating a cell which will not leak or corrode.

The conversion efficiency rate of the new solid-state solar cell is 10.2 percent, which is comparable to that of a Grätzel cell, though less than the rate of a conventional cell.
