Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The platform developed by the Brown School of Engineering lab of Rice materials scientist Jun Lou integrates catalytic electrodes and perovskite solar cells that, when triggered by sunlight, produce electricity.

Femtosecond Lasers Solve Solar Panels' Recycling Issue

Cars That Think

Solar panels are built to last 25 years or more in all kinds of weather. Manufacturers achieve the seal by laminating a panel’s silicon cells with polymer sheets between glass panes. But the sticky polymer is hard to separate from the silicon cells at the end of a solar panel’s life, making recycling the materials more difficult.

A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, very efficiently using light. Photosynthesis is the process by which chloroplasts in plants and some organisms use sunlight, water and carbon dioxide to create food or energy.

Researchers split water by altering photosynthetic machinery in plants; semi-artificial photosynthesis

Green Car Congress

A new study, led by academics at St John’s College, University of Cambridge, has used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies. —Sokó?
