Water and some nano-structured iron oxide is all it takes to produce bubbles of solar hydrogen. EPFL and Technion scientists just discovered the champion structure to achieve this In the quest for the production of renewable and clean energy, photoelectrochemical cells (PECs) constitute a sort of a Holy Grail. PECs are devices able of splitting water molecules into hydrogen and oxygen in a single operation, thanks to solar radiation. "As a matter of fact, we've already discovered this...

EPFL scientists are producing hydrogen from sunlight, water and rust - They're paving the way for an economic and ecological solution for storing renewable energy How can solar energy be stored so that it can be available any time, day or night, when the sun shining or not? EPFL scientists are developing a technology that can transform light energy into a clean fuel that has a neutral carbon footprint: hydrogen. The basic ingredients of the recipe are water and metal oxides, such as iron...

New Solar Cells Shine With Potential

Today´s solar cells have several limitations, including high production costs, low efficiency and durability, and reliance on scarce materials for production. Now, a group of Northwestern University researchers say they have developed a new solar cell that minimizes these problems. The device uses a Grätzel cell, a promising low-cost and environmentally friendly solar cell with a significant disadvantage: it leaks. The dye-sensitized cell's electrolyte is made of an...
