Researchers have developed a stable dye-sensitised solar cell that may turn out to be cheaper than silicon based cells.The all new Gratzel cell design , named after Swiss chemist, replaces silicon with Titanium-oxide semiconductor. This came out to be much cheaper, readily available and less toxic,thereby improving solar energy's green credentials.
However, there is one challenge with the new design--Its electrolyte is made of an organic liquid that leaks, threatning to corrode the cell.This problem has been resolved by the scientists with the use of the new material that solidifies, thus avoiding leaks and making solid state cell more stable.The material used is a thin film compound called CsSnI3- a combination of cesium, tin and iodine. It is addd in a liquid form to dye-coated nanoparticles and then it turns into a solid mass.
According to people associated with the project, this is the first demo of the solid state dye-sensitized solar cell that can definitely ensure better efficiencies than the present current solar technologies in the world..
