Solar-to-Hydrogen
Clean, renewable hydrogen can be produced by splitting water into hydrogen through an electrolyzer powered by solar energy. But a potentially cheaper and more efficient way to do this is to use photoelectrochemical (PEC) cells, which convert sunlight and water directly into hydrogen right there at the cell.

Solar-to-hydrogen cells can convert solar energy directly into hydrogen without needing an external electrolyzer, and an exciting new design out of the Australian National University has achieved record efficiency levels using low-cost materials.
