Metal-free carbon-based electrocatalysts for dye-sensitized solar cells (DSSCs) are active enough in one type of commonly used (cobalt-based) electrolyte but not in another (iodide-based) one. Now, researchers at UNIST in Korea say they may have overcome this problem with their new catalyst made from edge-selenated graphene nanoplatelets, which has a high power conversion efficiency (PCE) in both……..
