Researchers at Rice University have developed an efficient, low-cost device that splits water to produce hydrogen fuel.
Developed by the Brown School of Engineering lab of Rice Materials Scientist Jun Lou, the platform integrates catalytic electrodes and perovskite solar cells that, when triggered by sunlight, produce electricity.
The current flows to the catalysts that turn water into hydrogen and oxygen, with a sunlight-to-hydrogen efficiency as high as 6.7%.
Although this type of catalyst isn’t new, the lab packaged a perovskite layer and the electrodes into a single module that, when dropped into water and placed in sunlight, produces hydrogen with no further input.
