National Renewable Energy Laboratory (NREL) scientists have developed a proof-of-principle photoelectrochemical cell capable of capturing excess photon energy normally lost to generating heat. Using quantum dots (QD) and a process called Multiple Exciton Generation (MEG), the NREL researchers were able to push the peak external quantum efficiency for hydrogen generation to 114 percent. The advancement […]






Researchers at Caltech and the Berkeley Lab have in just two years nearly doubled the number of materials known to have potential for use in solar fuels. Using a new high-throughput method of identifying new materials, a team of researchers led by Caltech’s John Gregoire and Berkeley Lab’s Jeffrey Neaton and Qimin Yan have found […]






Ulsan National Institute of Science and Technology (UNIST) of Korea researchers have has introduced a new artificial leaf that generates hydrogen, using the power of the Sun to mimic underwater photosynthesis. The engineering offers a new artificial leaf that can convert sunlight into fuel with groundbreaking efficiency. This is a new take, looking at the […]






A promising, recently identified photocatalytic new material is inexpensive graphitic carbon nitride. The hunt is on for the storage of photogenerated electric energy and its release on demand are still among the main obstacles in artificial photosynthesis. Scientists are now exploring a modified form of graphitic carbon nitride that can produce light-generated electrons and store […]






Lawrence Berkeley National Laboratory┬áLaboratory scientists have found a way to engineer the atomic-scale chemical properties of a water-splitting catalyst for integration with a solar cell. The result is a big boost to the stability and efficiency of artificial photosynthesis. Led by researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), the project […]
