Scientists led by Germany’s Max Planck Institute for Solid State Research have demonstrated for the first time that, as well as electrons, light also releases charged particles in a perovskite solar cell material. The researchers state that this groundbreaking discovery could make possible new solar power applications, such as batteries directly charged by light.
Researchers from the Institute of Physics of the Polish Academy of Sciences (PAS) and the renowned Ecole Polytechnique Federale de Lausanne (EPFL) have collaborated on a new technique for the creation of perovskite solar cell materials. The technique replaces traditional solvent based processes with steel ball mill grinding.
A low-cost and ultra-stable perovskite solar cell, which was built by a team of scientists at Switzerland’s Ecole Polytechnique Fédérale de Lausanne (EPFL), has been operating at a constant efficiency of 11.2% for over a year with no performance loss.
