Rice scientists combine perovskite solar cells and catalytic electrodes to produce electricity

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. 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%.
