At the Laboratory of Photonics and Interfaces at EPFL, where scientists invented dye solar cells that mimic photosynthesis in plants, they have also developed methods for generating fuels such as hydrogen through solar water splitting.
Water and some nano-structured iron oxide is all it takes to produce bubbles of solar hydrogen.
How can solar energy be stored so that it can be available any time, day or night, when the sun shining or not?
Today’s solar cells have several limitations, including high production costs, low efficiency and durability, and reliance on scarce materials for production.
