By using a photoelectrode in which gold nanoparticles are loaded on an oxide semiconductor substrate, a research has worked to develop a method of artificial photosynthesis that may prove to be an excellent light energy conversion system.
The "artificial leaf" consists in principle of a solar cell that is combined with further functional layers. These act as electrodes and additionally are coated with catalysts. If the complex system of materials is submerged in water and illuminated, it can decompose water molecules. Show More Summary
A process for providing sensitive semiconductors for solar water splitting ('artificial leaves') with an organic, transparent protective layer has been developed by researchers. The extremely thin protective layer made of carbon chains is stable, conductive, and covered with catalyzing nanoparticles of metal oxides. Show More Summary
The team was able for the first time to produce a hybrid structure that converts 12 per cent of the incident solar energy into the form of hydrogen. The results have now been published in Advanced Energy Materials. read more
An international team has succeeded in considerably increasing the efficiency for direct solar water splitting with a tandem solar cell whose surfaces have been selectively modified. The new record value is 14 percent and thus tops the previous record of 12.4 percent, broken now for the first time in 17 years.
A new "artificial leaf" that can turn sunlight and water directly into hydrogen and oxygen is shattering performance and stability records
The big challenges standing in the way of a full frontal assault on petroleum by the clean energy industry are the cost of production and a dearth of ways to store the energy after its produced. But recently a team from Caltech’s Joint Center for came
To unlock the secret to renewable energy, science is taking a cue from nature.
A new solar fuel generation system, or artificial leaf, safely creates fuel from sunlight and water with record-setting efficiency and stability.
When we think of solar power, we usually think of solar panels but we should really be thinking about plants. After all, plants are the original solar power generators, turning the sun’s rays into energy through the process we all learned about in at
New research out of Melbourne has broken records and brought emission-less hydrogen energy a step closer to commercial production. Thom Mitchell reports.
“The aim of every artist is to arrest motion, which is life, by artificial means and hold it fixed so that a hundred years later, when a stranger looks at it, it moves again since it is life.” William Faulkner was known not just for long sentences, but also his ability to so luridly set […]
It seems like we are constantly getting a little bit closer to being able to live in outer space, but one teeny-tiny little detail keeps holding us back: oxygen. Plants just don’t like zero gravity environments, and toting around an indefinite oxygen supply
Engineers have taken a leaf out of nature’s book by equipping an artificial hand with muscles made from shape-memory wire. The new technology enables the fabrication of flexible and lightweight robot hands for industrial applications and novel prosthetic devices. Show More Summary
First came the artificial leaf, then came the bionic leaf, now make way for a "supersonic solar fuel cell" that uses sunlight to make hydrogen fuel Supersonic “Solar Fuel Cell” Could Churn Out Sustainable Hydrogen was originally published on CleanTechnica.

A graduate student working with the Tufts University silk lab has created an "artificial leaf" by extracting chloroplasts from plants and suspending them in a matrix of silk protein. When provided with water and exposed to light, the leaves will produce oxygen. Via Fresh Photons.
Researchers Peidong Yang, Bin Liu and colleagues may have found a way to mimic plants' ability to produce hydrogen from sunlight. Yang's team has used a process borrowed from the paper industry to create a flat mesh from light-absorbing semiconductor nanowires.
For years, scientists have been pursuing "artificial leaf" technology, a green approach to making hydrogen fuel that copies plants' ability to convert sunlight into a form of energy they can use. Now, one team reports progress toward a stand-alone system that lends itself to large-scale, low-cost production. Show More Summary
Generally speaking, the peculiar appearance of wind turbines coupled with the fact they perform better when up high and out in the open sees them banished to uninhabited countryside, or even out to sea. But a French entrepreneur believes...Show More Summary
In a twist on the "artificial leaf" theme, a research team from Australia has developed a new way to lower the cost of hydrogen for FCEVs, with solar power. Toyota Could Be Wrong About The High Cost of Hydrogen was originally published on CleanTechnica.
